Update [17/02] – Project redesigned, look this following post.
Update 27/01, I ‘ll finally use ESP8266 chip, for the same cost, Wifi connections on the probes will be more flexible, eliminate any constraints, quantity of probes, signal multiplexing, and data exploitation …
Under development, some wireless probe in the goal to send data’s, temperature and humidity level directly to arduino, with displaying on a 2×8 LCD in live, using NRF24L01+ RF chip and DS18B20, DHT22 probe. The board is compatible with both. Continuer la lecture de Wireless RF probe for Arduihome →
