Introduction

The Arduino compatible temperature sensors are a great way to measure the temperature of your environment. They are very easy to use and can be found for a reasonable price.

In this article, I will cover the 11 Arduino Uno Compatible Temperature Sensors. What is an Arduino compatible temperature sensor ? How does it work ?

What is a temperature sensor in general ?

The temperature sensor is the device that detects the temperature of an object or environment. They are used in various applications, such as home appliances, power plants, HVAC systems, weather forecasting, and air conditioning.

The temperature sensors are the devices which measure the temperature and transmit this information to a controller.

The temperature sensor can be either analog or digital in nature.Analog sensors use the voltage or resistance changes about ambient temperature changes, while digital sensors use microprocessors and logic circuitry to measure and store data.

Digital sensors are more precise than analog ones, but they are also more expensive and require more power consumption.

There are different kinds of Temperature Sensors like:

• Thermocouple Sensor
• Resistance Temperature Detector
• Infrared Thermometer
• – Differential Scanning Calorimeter
• Arduino temperature sensor

Different types of temperature sensors

Temperature sensors are used to measure and report the temperature of a material, object, or environment.

There are multiple types of temperature sensors on the market that can be categorized into three main groups:

A) Passive Temperature Sensors:

Passive temperature sensors do not require any external power source to operate and can be used in any environmental condition.

These sensors are usually made with the thermocouple, thermistor, resistance temperature detector (RTD), or thermopile.

B) Active Temperature Sensors:

Active temperature sensors need an external power source to operate and should only be used in controlled environments like laboratory settings.

Active temperature sensors include infrared (IR), microwave, laser-based pyrometry, and optical pyrometry.features temperature sensors Temperature sensors are used to detect ambient temperature. One can find these sensors in almost every electronic device, from laptops and smartphones to cars.

The temperature sensor is an electronic instrument that measures the temperature of its environment. The primary purpose of a temperature sensor is to measure the ambient air temperature.

Some common types of sensors include thermistors, thermocouples, and resistance thermometers.

Thermistors are the most common sensor used for measuring ambient air temperatures because they can be made cheaply and easily, have a wide range, and are sensitive enough for many applications.

The Arduino temperature sensor: The 11 Arduino Uno Compatible Temperature Sensors

The Arduino temperature sensor is a device that detects the temperature of its environment. It has a thermistor, a type of resistor that changes its resistance according to the temperature.

The Arduino can read this resistance and calculate the temperature based on the voltage it receives from the resistor.

There are many different sensors to get further readings, such as infrared, ultrasonic, and photoresistive. These sensors are used for many purposes, such as controlling heating or air conditioners, measuring humidity, and detecting motion, among other things.

Arduino Compatible Temperature Sensors for Your Arduino ProjectsThe Arduino Compatible Temperature Sensors are a cheap and easy way to measure the temperature of your environment.

The sensors range from -55°C to +125°C and can be used in any type of project. They work by sending an analog voltage between 0V and 5V, proportional to the temperature.

The DHT11 Temperature Sensor

The DHT11 is an inexpensive digital temperature and humidity sensor. It consists of a capacitive humidity sensor and a thermistor, which are sensitive to atmospheric moisture.

The DHT11 is an inexpensive digital temperature and humidity sensor. It consists of a capacitive humidity sensor and a thermistor, which are sensitive to atmospheric moisture.

The device has a range from 0°C to 50°C with an accuracy of ±2%RH (relative humidity) at 25°C or ±4%RH at any other temperature. The output data rate can be as fast as 20 readings per second with an update rate once every second.

The DHT22 Temperature Sensor

DHT22 is a sensor that can measure temperature, humidity, and air pressure. A digital sensor can measure these three parameters with an accuracy of ±2°C and ±5%RH, respectively.

This sensor is usually used in IoT or IoT applications to collect data from the environment.The temperature range is between -40 to 80 ºC +/-0.5ºC. The humidity range is between 0 to 100% +/-2%.

The DHT22 sensor is straightforward and does not require any additional components like resistors or capacitors. This makes it ideal for beginners looking to get started with electronics projects.

The LM35DZ Temperature Sensor

The LM35DZ is a sensor that can measure the temperature of the air and the surface around it. It has an output voltage that is linearly proportional to the temperature.

This voltage can be read through an analog input of a microcontroller. The Temperature range is between -55 to 150ºC.

This sensor is also known as an ambient thermometer and can measure indoor and outdoor temperatures.

It should not be used for high-temperature measurements because its linearity will break down at higher temperatures, but it’s perfect for measuring room temperature or outdoor temperature.

The TMP36 Temperature Sensor

The TMP36 is a popular temperature sensor that can measure ambient temperature.This is a type of analog sensor that has three pins.

Pin 1 is the power supply, Pin 2 is the ground, and Pin 3 is the signal output.The voltage at this pin will be proportional to the environment’s temperature surrounding it.

A resistance change in this resistor will change the voltage across it and cause a change in voltage at pin 3.An example of how this works would be if you were to put your hand on top of it, your body heat would cause an increase in temperature and thus a higher voltage output at pin 3.The Temperature range is between −40°C to +125°C

The LM335 Temperature Sensor

The LM335 is a temperature sensor that can measure the temperature in degrees Fahrenheit and Celsius. The sensor has a voltage output that changes with the temperature change.

This voltage is proportional to the change in temperature and can be used to measure this change by dividing it by an appropriate constant.The Temperature range is between -55 to 150ºC.

The LM34 Temperature Sensor

LM34 is a temperature sensor used to measure the temperature of a given object. It is also used for measuring the ambient temperature. LM34 has a linear output voltage that can be read by an analog-to-digital converter.

The LM34 has three pins: Vout, GND and A/D input pin. The Vout pin outputs the sensor’s voltage, and GND provides ground to the sensor.The Temperature range is between -55 to 150ºC.

The BMP180 Temperature Sensor

BMP180 is a sensor that can measure temperature, pressure, and humidity. It has an I2C interface and can detect changes in the environment.

The BME280 Temperature Sensor

This is a sensor that can be used to measure air pressure, temperature, humidity, and atmospheric pressure. The BME280 sensor is designed for low-cost, low-power, and low-sensitivity applications.

It can measure these factors with an accuracy of ±1 hPa for air pressure, ±0.2°C for temperature, and ±2% RH for humidity.

The BME280 sensor has an I2C interface, and it is compatible with any microcontroller that supports this bus protocol. The I2C interface allows multiple sensors to be connected to the same two pins (SDA and SCL).

This means that you could have four sensors on one single line: two on one side of the bus (A0 and A1) and two on the other side of the bus (A3 and A4). There are two pins for each side of the bus to which a sensor can connect.

These are called SDA and SCL, respectively. On the BME280, these pins correspond to digital input pins 0 and 1 on the Arduino board.The Temperature range is between -40 to 85ºC
