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 ...

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 ...

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 ...

These features allow one to effortlessly test and swap sensors, addressing the ESP32’s ADC limitations and ensuring ... they support up to 28-Gbps data transmission and a current capacity of 3.2 A ...

The ESP8266 and its heavyweight sibling the ESP32 are fantastic boards to develop with as they allow you to quickly and easily get a project online. Just tack a few sensors and some LEDs on them ...

The Tx, Rx and Ground pins are to be connected with the Rx, Tx & Ground pins of the UART sensors. This is shown in the schematic. The ESP32 is a 3.3 volt device. Therefore, the 5Volt signals of ...
