Recommended Essentials:
Perfect for your next weather station! This module includes all passives that you need to run the sensor directly on the module and only uses one pin to return the temperature and humidity!
This classic maker sensor is extremely well documented with many libraries for almost any microcontroller or single-board computer.
Specifications
- Voltage Input: 3.3-5V
- Temperature Range: -40~80°C, with ±0.5°C error
- Humidity Range: 0-100% RH with ±2% RH error
Examples
Raspberry Pi Pico - Micropython
