Hardware Monitor External Sensor External Sensor I2C/SMBus Output 20-SSOP

Monitoring Items
Temperature
Measure the temperature with high accuracy.
One thermal diode sensor (current mode) connected to CPU/GPU and one remote
sensor either by thermal diode (current mode) or thermistor.
Programmable hysteresis and setting points (alarm thresholds) for all monitored
items.
Voltage
3 voltage sensor inputs.
