Description:
    This module uses ESP8266-01/ESP-01S (without ESP-01S or ESP-01) as the master control, and DHT11 as temperature and humidity sensor.
    ESP8266 collects the temperature and humidity in the environment and uploads to the server. It supports 3.7v-12V DC power supply (3.7V lithium battery). It can be used as temperature and humidity collection node for smart home or IOT project.

Parameter:

NO. Parameter Value
1 Host ESP-01/ESP-01S (without ESP-01S or ESP-01)
2 Temperature and humidity sensors DHT11
3 Operating voltage DC 3.7V-12V (support 3.7V lithium battery power supply)
4 Measuring range 20-90%RH 0-50 Celsius
5 measuring accuracy Temperature: +/- 2, humidity +/- 5%RH


Application Example:
    1>. power supply: 3.7V-12V DC power VCC GND (pin 2.54mm) received.
    2>. download program to ESP-01S/ESP-01 (without ESP-01S or ESP-01).
    3>. insert ESP-01/ESP-01S (without ESP-01S or ESP-01) into the 2*4 Pin row (in the direction of the arrow).

About Connection:
    1>.TCP Server serial prints information
    2>.DHT11 client sends temperature, humidity, and count to the server
    3>.DHT11 add sleep function
    4>. Initializers the add restart function. If the connection fails 10 times, restart the module.
