The project involves using an RFID module, which can be easily interfaced with the Raspberry Pi. The RFID module typically used is the RC522, ... Raspberry Pi Ultrasound Sensor.

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users ...

Using RAIN RFID technology the Raspberry Pi HAT uses low-power consumption to read up to 200 tanks per 2nd thanks to its on-board M6E Nano RFID reader and ARM based Cortex M4 architecture.

Once you get these sensors, all you have to do is interface them with your Raspberry Pi and use software like Home Assistant or OpenHAB to run automations based on the sensors' readings.

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

The SENT protocol, standing for Single Edge Nibble Transmission, is used for sensors that need to send high-resolution data while keeping system costs low. It’s most typically used in the aut… ...
