High Accuracy Temperature Sensor Chip Mysentech M1601P with Single GPIO Port Communication Interface

M601, M1601, M1820 Series Digital High-Precision Temperature Sensor Chip

Product Overview
The M601, M1601, and M1820 series are high-precision digital-analog mixed-signal temperature sensor chips offering unparalleled accuracy of up to 0.1 without user calibration. Leveraging CMOS semiconductor PN junction temperature and bandgap voltage characteristics, these chips provide amplified, analog-to-digital converted, and digitally compensated temperature data via a digital bus. Key advantages include high accuracy, excellent consistency, rapid temperature measurement, low power consumption, flexible programmable configuration, and long operational life. With a built-in 16-bit ADC, they offer a resolution of 0.004C and an ultra-wide operating range from -70C to +150C. Each chip features a unique 64-bit ID sequence number, factory-tested and calibrated, with internal automatic compensation. The single-bus protocol simplifies system integration, requiring only one GPIO port for communication. This interface supports multi-node sensing and networking, enabling cost-effective, long-distance, and high-node-count distributed sensing networks, supporting up to 100 nodes in series over 100 to 500 meters. Integrated non-volatile E2PROM stores chip ID, alarm thresholds, calibration values, and user-defined information. The M601 series also includes an ALERT pin for hardware alarm extensions.
Applications: Smart Wearables, Electronic Thermometers, Animal Temperature Monitoring, Medical Electronics, Cold Chain Logistics & Warehousing, Smart Home Devices, Heat/Gas/Water Meters, and as a replacement for PT100/PT1000 sensors.
