Re: IOT Design for Agriculture

The wireless temperature sensors are specially designed to work through a wireless mesh network. The best part is battery cycle is much better than the mesh network with ESP8266 communicating with the gateway receiver can serially connect with raspberry pi and further you can use any kinds of advanc...

Re: First kit cheap sensor kit legit?

Hi, Rather than going on GPIO I should suggest that you should start interfacing sensors which have I2C compatibility which will also help you to know about the basic start and for first use, you should check out temperature and humidity sensor https://store.ncd.io/product/sht31-humidity-and-tempera...
