In this article, we will see how you can make a simple power consumption monitoring device using an ESP32 and some commonly available sensors. To begin with, our primary goal is to bring Voltage and ...

A 4-Channel mains sensor using an ESP32 two board versions one using a Wemos ESP32 the other uses a Node-MCU board. Both boards can work with either a current or voltage type of CT's (current ...

The ACS712 Current Sensor IC: As you can see in the above picture ... And as we are going to measure the current with an ESP32, it's only 3.3V tolerant, which is why I have used a voltage divider with ...

Uses INA226 sensor. Frequency counter with range 1Hz to 40MHz ... We can see that the DUT load current is ~10mA when the ESP32 is in deep-sleep. This residual current is due to the USB-UART IC and LDO ...

In his case, he used a YHDC SCT-013-030 sensor that can measure ... data he collects with his ESP32 energy monitor. Every 30 seconds, the hardware reports the current consumption to AWS through ...
