ESPr® Door sensor with ESP-WROOM-02

This product is a radio controlled door sensor with ESP-WROOM-02 Wi-Fi module and lead switch. You can get Open/ Close information by Wi-Fi. Please use Lithium-ion battery for power. You can switch from programming mode to running mode by replacing the jumper socket. You will need a Serial USB converter (5 V/3.3 V Selectable) for program storage. Please purchase magnet separately because it is not included. This sensor is designed to be applied for doors that close when it is in action like a bathroom door. Please be advised that it might misunderstand the command you give. Click for more details.

  • ESP-WROOM-02 WiFi module is loaded on Arduino compatible board. There are redundant pins on this board, because GPIO pins of ESP-WROOM-02 are lesser than Arduino. Only one A0 analog input pin. Although it is compatible to Arduino please be aware that it might not operate properly depending on choice of shield. Please refer to How to develop with Arduino IDE for more details. Operating voltage of input/output pin is 3.3 V.
