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.

Understanding Active & Passive Infrared Sensors (PIR) and ...

· While PIR sensors are excellent if you want to detect general movement, they don’t give you any more information on your subject. To know more, you’ll need an active IR sensor. Setting up an active IR sensor requires both an emitter and receiver, but this sensing method is simpler than its passive counterpart. Here’s how an active IR operates on a basic level: An IR emitter shoots out a ...
