Feature: This module is mainly controlled by ESP8266-01/ESP-01S, and DHT11 is a temperature and humidity sensor. The temperature and humidity in the ESP8266 acquisition environment are uploaded to the server. Support 3.7v-12V DC power supply (3.7V lithium battery). Can be used as a temperature and humidity collection node for smart home or IOT projects. ESP8266 ESP-01S: 1MB (8Mbit) Flash size. AP, STA, AP+STA modes available. Very simple AT commands, easy to use. Low-power consumption and small Internal LWIP interface. Only four pins interface, VCC-3V3, GND, TXD and RXD. AT commands firmware. New IC ESP8266ex This module just have small upgradation on ESP-01 PCB board Characteristic: Master: ESP-01/ESP-01S (This module does not include ESP-01/ESP-01S) Temperature and humidity sensor: DHT11 Working voltage: DC 3.7V-12V (supports 3.7v lithium battery power supply) Measuring range: 20-90% RH 0-50 C Measurement accuracy: Temperature: 2 C Humidity 5% RH Application example: 1.
