version v 1.2
TCP/IP voltmeter version v 1.2 has 4x DC voltmeter and 1x DC ammeter.
Usage
TCP / IP voltmeter is a universal device for measuring DC voltage and DC current, which has a built-in web server. Thanks to this, the measured values can be transmitted via the Internet. By measuring the current, we obtain additional data about the energy consumption of the measured device. The current measurement is performed by an external current sensor. 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 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.
