I thought I would share a a project that might be an interest to the community. I had a couple ST arrival sensor from back in the day. I used them in my car to track my car come and go. We got an additional car and need a new sensor. I found that they are discontinued and very hard to find.
I thought it would be fun to make one myself. I started to make one with the same functionality with the original ST arrival sensor with the following improvement. I use a recharge-able battery which will be filled up during a drive. I also use a powerful Zigbee module with an external module.
I added motion sensor and vibration sensor to help securing my car while it is parked outside the house.
Here is a short demo how it work. I am using Zigbee2Mqtt.
Here is one of the thing that I do with the sensor in automating my garage door. Warning: if you have amazon echo nearby, you may want to turn off the mic.
Here is how the sensor look like.
I made a handful of boards. If you are interested on testing it out please feel free to PM me. There will be reasonable cost for the sensor because I have to recover the component cost. I am just a hobbyist.
update: detail for driver and installation for the sensor.
update: Factory reset procedure.
update: I forget to mentioned that I uses Zigbee2Mqtt with sonoff zigbee 3.0 usb dongle plus as coordinator. I don’t have access to other type of Zigbee2mqtt compatible dongle at the moment to test.
update: Some insight on what make my sensor unique.
update: V2 board with boxes design for it.
update: Released sensor is available for purchase, PM me if you like to get one.
update: example of compatible battery.
update: Case options for Arrival Sensor.
Update: Zigbee2MQTT 1.25.2 include the arrival sensor converter as part of their release
Update: I just want to make sure that I mentioned that the sensor is DIY kit with component is soldered. A case may be needed to complete the sensor and ensure a nice and safe use.
