Great idea and super compact, wide range of input voltages and a reset button make this a great device!

Pros:
-cheap
-small
-easy to use

Cons:
-due to esp module placement the heat from the module greatly distorts the temperature data... (I fixed this with short male-to-female cables to distance the esp from the sensor, works but not super convenient)

Overall good product, maybe next time place the sensor and the esp socket to different sides so that temps are reliable? My temps are +8c over what they should be when esp is on top of the sensor

Good value for the money. Better with allowance.
Perfectly for the esp8266 small connections so the system fit in a small box.
I programmed Esp8266 an MQTT client and tested with a MQTT Dash App with an ESP32 as a poor man MQTT broker. It works well for a while and needs reset. More debug work needed.
Not great precision, needs calibration. I thought it was self heating. But the other DHT11 also has offset issues.
Thanks Bangood.

Q:
Hi. What is the function of the switch shown in the pictures?

Hi. What is the function of the switch shown in the pictures?
Hi. What is the function of the switch shown in the pictures?

A:

Switch pulls the reset line of the ESP-01 device used to Gnd and restarts the ESP program that is programmed in the ESP-01 WiFI Module. See the ESP-01 WiFi module for the pin signals available on the 2x4 yellow header. This module provides a 3.3 volt voltage needed to power the ESP-01 WiFi Module when plugged into the yellow header.
