WiFi sensor + Node-RED + Raspberry Pi | Raspberry Pi ...

· Make WiFi sensor and send data via MQTT. We use IOT Cricket WiFi module to make a sensor which will be sending a temperature value every 30 seconds to our system. It will run on a battery so we can stick it anywhere at home or a garden. Later you can also use Cricket to build various battery powered sensors, alarms, buttons, switches and connect them easily by using the same approach to Node-RED.
