The NST1001 is a NOVOSENSE D-NTC® series digital temperature sensor, with two pins and unique pulsecounting digital output, which makes it possible to directly connect to the GPIO of the MCU and save MCU resources to the greatest extent. The NST1001 has a high accuracy and high resolution over temperature range of -50°C to 150°C. NST1001 suits automotive, industrial, home appliances and other applications for temperature monitoring, the NST1001 chip can be easily used as a two-wire digital temperature probe or as a direct replacement for NTC thermistors. The NST1001 has a built-in EMI filter, which allows it to be used in devices with high interference. The NST1001 can also be used in wireless IoT sensor nodes with particularly stringent power requirements because of its extremely low operating current, which can be powered through the MCU's GPIO.
