- Product code: HCSENS0041
- Current sens max: +/- 3A
- Current sens voltage: 3 to 25V
- Sensor output: 1V / Amp
- Dimensions: 20mm x 19.5mm
Description :
- This module can be used to test the current and voltage.
- The principle of voltage test based on the principle of resistive voltage divider design can make the red terminal connector input voltage to 5 times smaller.
- Analog input voltages up to 5V, the voltage detection module input voltage not greater than 5Vx5 = 25V (if using 3.3V systems, input voltage not greater than 3.3Vx5 = 16.5V).
- AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V / 1023), so the minimum voltage of the input voltage detection module is 0.00489 Vx5 = 0.02445V.
- The MAX471 chip on the board used to test the consumed current of the load.
