Wifi Esp8266 Dht11 module Temperature Humidity WiFi Esp-01 Esp-01s
Description
This module uses ESP8266-01/ ESP-01S as main controller, and the temperature humidity sensor is DHT11. ESP8266 collects the environment temperature and humidity then upload to the server.
This module can be used as a temperature and humidity acquisition for smart home or IOT project.
Features
Master: ESP-01/ ESP-01S (the module does not include ESP-O1/ ESP-01S)
Temperature and humidity sensor: DHT11
Specifications
Working voltage: DC 3.7V-12V (it can be powered by 3.7v lithium battery)
Measuring range: 10-90% RH 0-50?
Measuring accuracy: Temperature: ±2? Humidity: ±5% RH
Application Examples
1. Power supply: 3.7V-12V DC power supply connected to VCC GND (2.54mm pin)
2. Download the program to ESP-01S
3. Insert ESP-01/ ESP-01S into the 2 * 4 Pin (in the direction of the arrow),
ESP8266 Esp-01 Serial Port WIFI Transceiver Wireless Module
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete
and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi
networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the
sensors and other application specific devices through its GPIOs with minimal development up-front and
minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry,
and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Warnings:
This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolant. Connect RX or TX on 5V Arduino will
destroy this module. You must use a logic level converter, or a 3.3V Arduino
The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module. You must provide a separate,
higher 3.3V supply(about 300mA or better)
The ESP8225 module is very new on the market and support and documentation for it is currently very limited.
