Power Monitor HAT is the latest product in the domain of SB Components that is the 3 Channel Current/Voltage/Power Monitor HAT For Raspberry Pi. It uses the I2C or SMBus interface for lightweight communication. It makes the process easy to monitor current, voltage, or power in each channel and also monitor the voltage between both sides of the sampling resistor.

Features:

• It has the standard Raspberry Pi 40PIN GPIO extension header from which it can be stacked on Raspberry Pi easily. It supports all the variants of Raspberry Pi boards.
• Power Monitoring HAT comprises Embedded ADC of 12 bits that convert the analog signal into a digital signal. Power monitoring HAT is developed to support multiple successive converting with the 0~26V voltage measuring range.
• There is a sampling resistor that is onboard, 0.1Ω 1％ allows measuring bi-directional current up to 3.2A in the channel.
• It provides the monitoring on 3 channels. It performs the task via the I2C/SMBus interface that makes the process happen on the low bandwidth.
• This HAT consists of I2C control pins for connecting with other host boards to perform the task as per the requirement.
• It can directly calculate electrical quantities like power, voltage, and current. Power Monitoring HAT measures output power value through an additional multiply register that helps the user to get the right readings.
