Measure Temperature with a Sensor Made for Embedded Builds
The Temperature and Humidity Capacitive Digital AM2302 DHT22 Sensor is a temperature and humidity sensor with 1-wire designed for climate logging, weather nodes, and room monitoring. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Interface: 1-Wire.
Important: Sensor response time depends on airflow, mounting, and thermal contact. Keep heat sources and self-heating from nearby parts in mind.
Why you’ll love it
- Key feature: 2.5mA max current use during conversion (while requesting data)
- Good: Good for 0-100% humidity readings with 2-5% accuracy
- 27mm wide x 58.75mm tall x 13.30mm deep: 27mm wide x 58.75mm tall x 13.30mm deep
- Easy wiring: 1-Wire
- Maker-friendly build: Easy to use in prototypes, classroom projects, and custom electronics
- Common controller support: Works well with Arduino, ESP32, Raspberry Pi, and similar boards
