Parkside PLEM 50 C2 laser range finder UART Integration for ESPHome
Parkside PLEM 50 C2 is a cheap (around €30) laser finder. I find this one very useful for monitoring water levels in water tanks and drainages.
The device consist of laser sensor module and main PCB + display module. Laser module is connected to main board with 4-conductor 1mm FFC cable - UART interface.
For ESPHome integration we need the laser sensor module only.
Pinout of the FFC (left to right):
- GND
- VCC (3.3V)
- Rx (connect to ESP Tx)
- Tx (connect to ESP Rx)
See here for how to use external components. See the example configuration file.
