DHT11 Temperature and Humidity Sensor
$5.45The DHT11 Temperature and Humidity Sensor is a low-cost and widely used sensor for measuring temperature and humidity in various applications. It is a combined digital temperature and humidity sensor that provides accurate and reliable data in a compact package. The DHT11 uses a capacitive humidity sensing element and a thermistor to measure the relative humidity and temperature, respectively. The sensor provides a digital output via a single wire interface, making it easy to connect to a microcontroller or other digital circuit. The DHT11 supports a temperature range of 0°C to 50°C and a humidity range of 20% to 90% relative humidity, making it suitable for use in a wide range of indoor and outdoor environments.

DHT22 Temperature and Humidity Sensor Module
$17.44DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It’s fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Thermistor 10K
$0.55The Thermistor 10K is a temperature-sensitive resistor used in electronic circuits for measuring temperature. It consists of a metal oxide material that changes resistance in response to changes in temperature, making it an ideal sensor for temperature measurement and control. The 10K value indicates the nominal resistance of the thermistor at 25°C (77°F), and the resistance of the thermistor will change as the temperature changes. The thermistor is a passive component, meaning that it does not require an external power source to operate, making it ideal for use in battery-powered and energy-sensitive applications.
