How to use NTC Thermistor to measure Temperature? - A blog
Dec 23, 2019I recommend you to add a 16X2 LCD Display Shield which can be directly fit on to the top of the Arduino board without the need of extra wiring for the LCD Display. Without the LCD Display, you can only monitor the measured current value on PC via Serial Monitor. You can get the LCD Display board at our affiliate link here !!!.
PZEM-0xx power monitor - Tasmota - GitHub Pages
Wiring Diagram: * Check images below for more information about the 1kOhm resistor needed to use 3 instead of 5V for the PZEM-004T serial connection. PZEM-016 modules can be converted from RS485 to TTL serial level devices by simply removing the internal MAX485 chip and adding two internal jumper wires. This will bring the serial port
