TCP/IP voltmeter device
version v 1.1
TCP voltmeter
This TCP voltmeter is designed to measure DC voltage and transmit data over the Internet.
TCP/IP voltmeter version v 1.1 has 4x analog inputs (4x DC voltmeter)

Usage

TCP / IP voltmeter is a universal device for measuring DC voltage, which has a built-in web server. Thanks to this, the measured values can be transmitted via the Internet. The use is mainly in measuring and monitoring voltage at a distance. It is suitable e.g. for measuring batteries in solar systems and other devices that are powered by batteries.

The TCP / IP voltmeter has low power consumption ( 0.8 Watt ) and includes many advanced features such as storing data in the cloud or MySQL database and sending alerts in various situations.

Hardware

The board contains a 3.3 V power supply, a 32-bit PIC32MX130 microprocessor, A/D converters, an optical I2C bus isolator and an ethernet controller. After connecting the ethernet cable and power supply, the board is ready for use.

The board is powered by an external voltage of 5 - 28V DC. Consumption is approximately 0.8 Watt. The analog inputs are galvanically separated from the rest of the board, so there are no problems with different GND potentials.

The board is designed for indoor use. For outdoor use, it is necessary to protect the device from water and high temperatures.
