Review on 🌑️ Songhe AHT10 High Precision Digital Temperature Humidity Sensor Module - I2C Communication, 1.8-6.0V, Replace DHT11 SHT20 AM2302 - Pack of 3 by Gordon Turman

Revainrating 3 out of 5

Information most people need to use this module effectively.

Media could not be loaded. I only gave it 3 stars because there isn't enough information for those who really want to use it in real circuits. The attached video shows the chart (I really don't understand why sellers don't provide charts). The XC6206-3 is a 3.3V output voltage regulator. The Vin of the circuit needs to be about 100mV above the 3.3V output voltage for it to work. Connecting Vin to 3.3V on any CPU board will likely result in unreliable operation at best, or more likely no communication with the AHT10. Supplying Vin with 5V works fine. As you can see there are pull-up resistors for the I2C lines. They may suffice if the processor board does not have resistors on the I2C pins.

Pros
  • Check, measure and check
Cons
  • Out of mode
