LM35 Temperature Sensor
The LM35 is a cheap and easy to use analog temperature sensor found in many Arduino Kits. Let's find out how to use it.
HTU21D Humidity Sensor
Interested in sensing environmental data? Let's have a look at another humidity and temperature sensor: the HTU21D.
DHT11 and DHT22 Humidity Modules
Do you want to measure humidity and temperature for one of your projects? The DHT11 and DHT22 are a popular choice.
DS18B20 Temperature Sensor
Want an easy-to-use digital temperature sensor? The DS18B20 is a popular alternative to analog temperature modules.
Temperature Threshold Module
Do you want to trigger an action once the temperature crosses certain point? Then you are in need of a temperature threshold module.
Analog Temperature Modules
Do you need to know the temperature for one of your Arduino projects? In this tutorial we learn how to use analog temperature modules.
Temperature Measurement with NTCs
NTCs are often used as temperature sensors. To use them, we need to know how to calculate a temperature value out of the measured resistance.
The resistivity of materials is dependent on temperature. Thermistors are electric components which make use of this.
