ESPHome mmWave Presence Sensor Case

prusaprinters

My ESP32 board has 30 pins and measures about 29mm x 52mm. I had to remove the pins to make the whole assembly thin. I wasn't happy with how large the other enclosures that I could find were. I also didn't find many cases that fit the LD2420 module. I placed the PCBs side by side so I could bridge the 3.3v and GND.My modules had firmware 1.5.9. The case press fits, you may want/need to drill the holes to get it to fit.Here's my yaml for configuring the board with the wiring shown (for my firmware) in the photos for anyone that wants to skip the learning stage of doing one of these.uart: id: ld2420_uart baud_rate: 115200 tx_pin: GPIO16 rx_pin: GPIO17 parity: NONE stop_bits: 1 ld2420: text_sensor: - platform: ld2420 fw_version: name: LD2420 Firmware sensor: - platform: ld2420 moving_distance: name : Moving Distance binary_sensor: - platform: ld2420 has_target: name: Presence select: - platform: ld2420 operating_mode: name: Operating Mode number: - platform: ld2420 presence_timeout: name: Detection Presence Timeout min_gate_distance: name: Detection Gate Minimum max_gate_distance: name: Detection Gate Maximum # See "Number" section below for detail gate_select: name: Select Gate to Set still_threshold: name: Set Still Threshold Value move_threshold: name: Set Move Threshold Value button: - platform: ld2420 apply_config: name: Apply Config factory_reset: name: Factory Reset restart_module: name: Restart Module revert_config: name: Undo Edits
