Humidity and Temperature Sensor Module

Description

Measure temperature and relative humidity using a simple interface that requires just three wires to the sensor: GND, power, and data. Supported by an Arduino library that makes it very easy to read values into your project, so with a single I/O line from your microcontroller you can read both temperature and humidity.

The module includes mounting holes suitable for M3 or 1/8″ bolts, and a flat rear face so you can easily glue it to any surface.

Features

• DHT22 sensor
• -40°C to +80°C temperature range with +/-0.5°C accuracy
• 0-100% relative humidity with 2-5% accuracy
• 0.5Hz sample rate (one sample every 2 seconds)
• 3 -5V operation
• Power consumption just 4.3mA during reads, even less when idle
• Blue power LED
• Dimensions: 31(W) x 23(H) x 4(D)mm
