ESP8266 Wifi NodeMCU Smart Home IOT DIY Kit ESP8266 ESP-01 DHT11 Temperature Humidity Sensor Module

Description:

• This module uses ESP8266-01 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 3.7 v-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:

• Host: 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

Application example:

• power supply: 3.7V -12V DC power VCC GND (pin 2.54 mm) received.
• download program to ESP-01.
• insert ESP-01 into the 2*4 Pin row (in the direction of the arrow).

About Connection:

• 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
