This module is designed to sense temperature and humidity. It is used with an ESP-01 module (not included.) This module has WiFi capabilities integrated so it’s possible to create a network of sensors within range of a wifi router. The data they collect can be passed internally on the LAN or passed to a server for logging or to trigger an action.
The module accepts a wide voltage range and is designed to be powered from a lithium battery directly if desired.
The sensor integrated is a DHT 11. It has moderate accuracy.
- Measuring Range: 20-90% RH 0-50℃
- Measurement Accuracy: temperature: ±2℃, humidity ±5%RH
