Additional Details

The ZS18B20B is a high-precision digital temperature sensor IC designed for industrial monitoring, distributed temperature measurement, and embedded electronic applications.

Combining analog temperature sensing with digital signal processing, the sensor provides an accuracy of ±0.5°C across the -10°C to +85°C range, with an overall measurement range of -55°C to +125°C.

Each sensor undergoes factory testing and calibration, with internal compensation calculations automatically correcting temperature measurement errors. This eliminates the need for additional user calibration.

The ZS18B20B features a standard 1-Wire digital communication interface, allowing multiple sensors to communicate over a shared data bus. Sensor identification, temperature readings, memory access, and configuration are handled through digital commands, requiring only a single GPIO pin on the host microcontroller.

Each chip includes a unique 64-bit identification number and dedicated nonvolatile EEPROM memory for storing temperature alarm thresholds, calibration correction values, and user-defined information such as sensor node numbers and installation locations.

Designed for compatibility with existing DS18B20 systems, the ZS18B20B supports nearly all standard DS18B20 communication timing requirements and can generally be integrated into existing DS18B20 software without modification. Its TO-92 package uses the same pin configuration, enabling pin-for-pin hardware replacement.

With its 500 ms temperature conversion time, 12-bit resolution, and 2.5–5.5 V operating voltage range, the ZS18B20B is suitable for industrial monitoring systems, smart hardware, agricultural monitoring, instrumentation, and other distributed temperature-sensing applications.

Additional Details

The ZS18B20C is a high-precision, 12-bit digital temperature sensor IC designed for industrial monitoring, distributed temperature measurement, and embedded electronic applications requiring flexible power configurations.

Combining analog temperature sensing with digital signal processing, the sensor provides an accuracy of ±0.5°C across the -10°C to +85°C range, with an overall measurement range of -55°C to +125°C.

Each sensor undergoes 100% factory testing and calibration. Internal compensation calculations automatically correct temperature measurement errors, eliminating the need for additional user calibration.

A distinguishing feature of the ZS18B20C is its support for two-wire parasite-power operation, allowing the sensor to draw power through its data connection rather than requiring a dedicated external power supply wire. This simplifies wiring and installation in distributed sensor networks.

The sensor uses a standard 1-Wire digital communication interface, enabling multiple sensors to communicate over a shared data bus. Sensor identification, temperature readings, memory access, and configuration are managed through digital commands, requiring only a single GPIO pin on the host microcontroller.
