Description

 

EMIS, Energy Monitor IoT Sensors board, based on an ESP32 WROOM, designed to monitor AC or DC Current, with interfaces to RS232 and RS485.    This board is designed to interface any Home Automation System.

  • An I2C reversible 2.54mm header is provided in the middle of the board, which will allow an OLED display (such as a SSD1306 I2C), to be directly mounted / connected on the board.  OLED not included.
  • Large Quality Terminal Block is included, which are suitable for 20 AWG up to 6 AWG, 10mm², together with smaller terminal blocks for DC supply, Relay etc.  These are not populated, so you may optionally solder cable tails directly to the PCB.
  • Power for the board may either be provided via the Micro USB (for flashing, debugging etc.), and/or via a terminal block for normal operation.  DC input has a range of 7V, through to 15V maximum.

 

The EMIS board is suppled fully tested.
