You can use a straight 17cm copper wire for this.(see product photos) Measuring range temperature: -40 ~ +80 ☌.įile name: DHT22 temperature-humidity sensorĤ33Mhz RF transmitter and receiver link kit.Humidity measurement range: 0% ~ 100% RH.This is a lot more accurate than the DHT11. Measurement range Temperature: 0 ~ +50 ☌įile name: DHT11 basic temperature-humidity sensorĪ handy temperature sensor and humidity sensor.Measurement range Humidity: 20% ~ 90% RH (0-50 ☌ temperature compensation).The possibilities with this module are endless! This variant has 1MB of memory instead of the 512kB on the standard ESP8266 module.ĭownload this part at my GitHub library here.
The ESP8266 module works with the normal UART port on your Arduino and can connect to networks, form your own network (hot spot) or both. This “S” version of the ESP-01 module has minor improvements in the PCB compared to the normal ESP-01 module. This module offers you the possibility to connect your Arduino to WiFi for a very low price.
