Energy Meter 100 A – TTL output
The readings can be taken over the TTL interface, using Arduino (or another microcontroller) or a PC, through a serial-to-USB converter.
SKU 2846-PZEM004TEAN 8219671059046Item type: AssembledSensors
Description
Composed of a voltage/current sensor with TTL output and a current transformer, this energy meter allows measuring, without interrupting the cable: AC voltage, AC current, active power, frequency, power factor. Data can be read via the TTL interface, using Arduino (or another microcontroller) or a PC, via a serial-USB converter.
Technical specifications
- Power factor range (ratio of active power to apparent power): 0.00 to 1.00 / Resolution: 0.01 / Accuracy: 1%
- Communication interface: TTL – baud rate 9,600, 8 data bits, 1 stop bit, no parity
Documentation and useful links
- PZEM004Tv30 library is used for serial communication with the sensor
- Every library is instead used to run blocks of code at regular intervals without using delay().
