Description

This breakout board carries a DHT22 onboard and facilitates connections to the sensor using a male, 4-pin, 90-degree, 0-1″-pitch header that can be plugged into a breadboard or directly onto a microcontroller (e.g., Arduino) or single-board computer (e.g., Raspberry Pi). The board also includes a 4mm-diameter mounting hole for easy affixing to any flat surface. A set of 3 female-to-female, Dupont jumper wires are included for making the connections.

The fantastic DHT22 onboard temperature and humidity sensor comes enclosed in a plastic permeable casing that allows it to measure the surrounding air while being resilient to damage by changes in the environment. The casing protects the electronics inside while allowing air to pass through for measuring temperature and humidity.

Because the measured data is transmitted digitally, there is no signal degradation over long distances. The data transmission uses a 1-Wire proprietary protocol, for which Open-Source libraries are available for platforms such as Arduino boards, ESP8266, Raspberry Pi, and other microcontrollers and single-board computers.

Features:

  • Usable temperature range: –40~80°C and 0~100% RH
  • Resolution: 8-bit
  • Communication: 1-Wire protocol
  • Accuracy: ±0.5°C in the range –10~80°C and 5% in the entire RH range
  • Operating Voltage: 3.3~6V (power/data)
