Description

The DHT22 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.

 

  • Power supply: 3- 5V.
  • Current: 2.5mA max use of current during conversion (while requesting data).
  • Humidity: 0 - 100%, ± 2%.
  • Temperature: -40°C + 125°C, ± 0.5%.
  • The sampling rate no more than 0.5 Hz (once every 2 seconds).

Waterproof DS18B20 Digital Thermal Probe or Sensor

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances!
