ESP32 Temperature and Humidity Meter with Real-Time Display

temperature and humidity meter

Are you looking for an easy project to monitor environmental conditions in real-time? This project will show you how to create an ESP32 Temperature and Humidity Meter whose readings will be received in real-time. This small, inexpensive project requires the ESP32 microcontroller, CHT8305 temperature and humidity sensor, a 20×4 I2C LCD display, and a DS3231 Real-Time Clock (RTC) module. The system toggles: it will present the current temperature, humidity, date, and time for 10 seconds and then show the maximum and minimum values of the temperature and humidity for 5…

Three Phase AC Voltage Measurement using Arduino

Three Phase AC Voltage Measurement using Arduino prototype

Today, in this article, you will learn how to make Three Phase AC Voltage Measurements using Arduino. At first, we will show you how to measure single-phase AC voltage and then measure three-phase AC voltage. Features of Three Phase AC Voltage Measurement using Arduino: Can measure AC voltage of any amplitude. Show individual phase voltage. LED indication for individual phase voltage. For the protection of the control board (Arduino Board), a variable resistor is used i.e. output voltage must not be more than 4.5V even when Zener diode burnout. Working…
