Gravity: DHT22 Humidity and Temperature Sensor
Overview
The SEN0137 is a digital humidity and temperature sensor module based on the DHT22 sensor, designed for the DFRobot Gravity ecosystem. It provides accurate environmental monitoring over a single-bus interface and is pre-mounted on a carrier board for rapid prototyping. The module operates at up to 5V and features a measurement range of -40 to 80 degrees Celsius and 0 to 100 percent relative humidity.
Why Choose This Part
This module features a 2 percent accuracy rating and a wider measurement range than the standard DHT11. The Gravity interface simplifies wiring with a plug-and-play 3-pin connector, eliminating the need for external pull-up resistors or complex breadboarding.
Applications
Key Specifications
Getting Started
Connect the module to an Arduino using the provided Gravity cable and use the DHT library to read data via the single-bus interface. The sensor is compatible with 3.3V and 5V microcontrollers, though it is typically used with 5V Arduino boards for best performance.
