ESP8266 ESP-01 ESP-01S with DHT11 Temperature and Humidity WiFi Node Module

This module uses ESP8266-01/ESP-01S (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.

Parameters:

• Host > ESP-01/ESP-01S (random send ESP-01S or ESP-01)
• Temperature and humidity sensors > DHT11
• Operating voltage   > DC 3.7V-12V (support 3.7V lithium battery power supply)
• Measuring range    > 20-90%RH 0-50 Celsius
• Measuring accuracy >Temperature: +/- 2, humidity +/- 5%RH

• Power supply: 3.7V-12V DC power VCC GND (pin 2.54mm) received.
• Download program to ESP-01S/ESP-01 (random send ESP-01S or ESP-01).
• Insert ESP-01/ESP-01S (Note : randomly sent ESP-01S or ESP-01) into the 2*4 Pin row (in the direction of the arrow).

• TCP Server serial printsinformation
• DHT11 client sends temperature, humidity, and count to the server
• DHT11 add sleep function
• Initializes the add restart function. If the connection fails 10 times, restart the module
