How to measure DC and AC current using HSTS016L Hall Effect Current Transformer – A blog about DIY solar and arduino projects (solarduino.com)


The rated output for the HSTS21 split core hall effect sensor is 2.5V ± 0.625V123. The rated input for the 600A model is ±600A123. Therefore, the output voltage per ampere measured would be (2.5V ± 0.625V) / (±600A). This simplifies to (4.17 ± 1.04) mV/A. Please note that this is an approximation and the actual output voltage per ampere may vary depending on the specific conditions of use.

SRS Thermistor Calculator (thinksrs.com)

Using the Steinhart-Hart model coefficients for the NCT 10500 OHM thermistor that I provided earlier, we can calculate the resistance values for the given temperatures. Here are the results:
At 4°C, the resistance of the NCT 10500 OHM thermistor is approximately
1,008.6
ohms1.
At 21°C, the resistance of the NCT 10500 OHM thermistor is approximately
1,000.0
ohms1.
At 60°C, the resistance of the NCT 10500 OHM thermistor is approximately
966.5
ohms1.
I hope this helps!
