2. Connect the board
Plug the board into the computer with the USB-C cable from the kit (some phone-charging cables have no data wires and will not work).
Press Install below, pick the port that appears (often "USB JTAG/serial debug unit" or "USB Serial"), then Connect.
No port in the list? Hold the board's BOOT button, tap RST, let go of BOOT, then press Install again.

3. Check it worked
When it says Installation complete, press RST on the board once.
Press Install again, then Logs & Console. You should see a line of readings about once a second. Kits with a settings step (Fall Guardian, LiDAR Doorway, Mains Clamp) take typed commands here, as your setup guide explains.
Safety and limits: these are maker/experiment kits. Not medical devices, not alarms, not certified measuring instruments. Mains Clamp: never open a consumer unit, socket or plug.
Firmware is built from the Sensor Shop sources with Arduino-ESP32 3.3.12. Each kit's file and SHA-256 prefix are listed above. Installer: ESP Web Tools 10.4.0 (Apache-2.0).
