NST1002:High-precision Single-BUS Digital Temperature Sensor

For wearables, glucose monitoring

The NOVOSENSE NST1002 is a high-precision, low-power temperature sensor that can sense changes in ambient temperature or body surface temperature in real time and adjust the algorithm accordingly to make glucose monitoring more accurate.

NST1002 is a high-precision dual-pin single bus-type temperature sensor. NST1002 has a single bus protocol output interface and high precision in a wide temperature range. It can be directly connected with MCU to ensure the measurement accuracy and reduce the overhead. The NST1002 device supports a maximum accuracy of ±0.5°C over temperatures ranging from -50°C to 150°C, while providing extremely high resolution (0.0078125°C) without system calibration or hardware/software compensation. The digital interface of the single bus protocol is designed to connect directly to GPIO, simplifying hardware design. The simple dual-pin architecture enables the NST1002 device to be easily converted into a two-wire temperature probe.
