HK1020 single bus digital temperature sensor

Category:

HK1020 is a digital temperature sensor that provides 9~12-digit temperature measurement accuracy and user-configurable high and low temperature alarm thresholds. Communication with the microcontroller is via a single bus interface. HK1020 can work in two modes: external power supply and parasitic power supply. One microcontroller can be used to control multiple devices at the same time to achieve temperature detection in a large space area. Due to its wide operating voltage range, low power consumption and single bus interface, HK1020 is very suitable for use in various temperature control systems.
