Review on DollaTek Temperature Humidity Wireless Transceiver by Eric Rios

Revainrating 3 out of 5

Inaccurate temp reading due to design

Build works well with blue power LED and reset button. The sensor is connected to GPIO2 on the ESP-01 module. However, there is an issue with heat affecting the sensor's temperature reading. There are two heat generators in this assembly: a voltage regulator on the board and an ESP module. Both generate enough heat to be absorbed by the sensor, affecting the temperature reading. Bending the sensor so that it is far from the base board does not solve the problem - heat enters through the 4 pins of the sensor.

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous
