And using ads1115 for external adc bcs esp32 isnot quite good. In that case, can we not directly connect bare ends of the cut wire of SCT-013-020 directly to our microcontroller? The project uses the YHDC SCT-013-000 clamp on current sensor to read the current on the mains line. Burden resistor and an voltage devider to create an analog value between 0 -> 5V. In this case a SCT-013-000 CT-clamp with burden resistor, 50Hz signal, ADS1115 (or 1015) and a PoE powered ESP32, monitoring the current through a 230V live wire in a circuit breaker box. 0; const However. Schema: I don’t have a good picture to share but you can refer to the guide or Energy Tracking with ESP32 + CT Clamp Sensor from an Efergy elite 1. Now let's say there's a SCT-013-000 (with load resistor) connected to two inputs of the ADC for differential measurement, would I be correct in saying that putting something like a CD4066 between the ADC and SCT-013-000, and on the same power supply as the ADC It depends on the application and operating environment. Instructions for setting up ct clamp sensors. Setup is with ESP32-S2 (NodeMCU) with ADS1115. Below are the scenarios I have tested so far: SCT013 - 30A/1V => Zero output SCT013 - 100A/50mA => Zero output with burden resistors ( 22 Ohm) SCT013 - 100A/50mA => Getting some readings without burden resistor. We will use a sensor with voltage output ± 1V RMS and internal burden resistance, together, with an ADC like the ADS1115 in differential mode. Connect the SCT-013 voltage output to ADS1115 ADC channel. I want to monitor current of three phases (SCT clamp sensors) and voltage (ZMPT sensor), all outputing voltage. But i have problems with the measurement. # Example configuration entry sensor: - platform: ct_clamp sensor: adc_sensor name: "Measured Current" update_interval: 60s # Example source sensor - platform: adc pin: A0 id: adc_sensor I am having limited success and non-linear readings.
