Temperature Sensor Mysentech DS18B20A10T6 with Waterproof Design and Multi Node Network Capability
Product Overview
The MYDS18B20 series digital temperature probes, featuring the MYDS18B20/MY18E20 chips, offer high-precision digital temperature sensing with an accuracy of 0.5 within the -10C to +85C range. These probes utilize a CMOS semiconductor PN junction temperature principle, processed through signal amplification, analog-to-digital conversion, and digital calibration for a stable and reliable output. The chips support a standard single-bus communication interface, enabling multi-node sensing and networking with a single GPIO port. They are designed for low power consumption, wide operating voltage (1.8V-5.5V), and feature built-in non-volatile E2PROM for storing ID, alarm thresholds, and user-defined information. Applications include industrial monitoring, smart hardware, smart agriculture, instrumentation, and smart home appliances.
