AM2302 DHT22 ESP8266 ESP-01/01S Temperature Humidity Sensor Wifi Wireless Module
ESP-01 ESP-01S DHT22 Temperature Humidity Sensor
Introduction
This is a calibrated digital temperature and humidity sensor for detecting ambient temperature and humidity, using DHT22 (AM2302), standard single bus interface.
Compared with DHT11, it has higher precision and larger range.
Can be used with the ESP-01/ESP-01S WIFI module and can replace the SHT11 SHT15.

ESP-01/01S Adapter

Description:
This is a breadboard adapter for the popular ESP-01 model of the ESP8266 serial-to-WiFi transceiver module.
As ESP-01 Pin arrangements are not breadboard friendly and are not labeled, which makes it little inconvenient for rapid prototyping.This breadboard adapter will help you to make
prototyping with esp-01 module much more easier.
This breakout conveniently offers clear pinout silkprint on top and will nicely fit your prefered breadboard.
Last but not least, we added a 0.1µF decoupling capacitor so the ESP-01 will always run smoothly and without a hitch.
