## Description

Measure temperature and relative humidity with this simple, Arduino-compatible sensor module based on the DHT22. With just three connections (GND, power, and data), you can read both temperature and humidity from a single I/O pin on your microcontroller. An Arduino library is available to make integration quick and easy. The module includes mounting holes for M3 or 1/8" bolts and a flat rear face, so it can be easily bolted or glued into your enclosure. Designed and made in Australia by Freetronics. Key Features DHT22 Sensor – Reliable combined temperature and humidity measurement Simple 3-Wire Interface – GND, power, and a single data line Wide Voltage Range – 3–5 V operation for flexible integration Low Power – Just 4.3 mA during reads, even less when idle Blue Power LED – Visual indicator that the module is powered Mounting Holes – M3/1/8" bolt compatible for secure installation Specifications Temperature Range: −40 °C to +80 °C (±0.5 °C accuracy) Humidity Range: 0–100% RH (2–5% accuracy) Sample Rate: 0.5 Hz (one reading every 2 seconds) Operating Voltage: 3–5 V DC Current Draw: 4.3 mA (reading), less when idle Dimensions: 31 × 23 × 4 mm Ideal For Weather stations and environmental monitoring Arduino and microcontroller projects requiring climate data Greenhouse and terrarium automation Indoor air quality monitoring Package Contents 1× Humidity and Temperature Sensor Module (DHT22-based) Resources Quickstart Guide (Freetronics) Schematic and Reference (PDF) DHT22 Datasheet (PDF) Design Files (GitHub)
