M117 M117B High Precision Digital Thermometer
■M117 is MinYuan fourth generation of digital high-precision temperature sensor with a typical temperature measurement accuracy of 0.1 ℃. The temperature sensing principle is based on the characteristic relationship between the semiconductor PN-junction temperature and voltage, through small signal amplification, analog to digital conversion and digital calibration, the 16-bit digital temperature data can be easily accessed. It has strength of high accuracy and consistency, long lifetime, low power consumption, programmable configuration flexibility. The thermometer integrates an EEPROM as a storage for ROM ID of the sensors, temperature alarm threshold, temperature calibration correction values and user-defined information such as sensor node information. Each sensor IC has a unique 64-bit serial number as ROM ID, and is fully calibrated before ship out. The IC has I2C interface for the host processor to access.
■High-precision temperature measurement region can be customized upon requirement. For example,for wearable thermometer and cold chain logistics range, the in-fab calibration procedure is different. Therefore the product series is divided into classes of 0.1 ℃ /0.5 ° C for different working conditions and precision requirement at different price, as shown below.
●Features:
■Highest accuracy: ±0.1°C, (or ±0.5°C, accuracy in the product series)
■-70°C~+150°C working temperature range
■The standard to the series has a default 16-bit ADC output, with a maximum resolution of 0.004°C
■Configurable conversion time: 10.5ms/5.5ms/4ms
■Configurable single shot mode and periodic data acquisition mode
■User configurable alarm threshold
■32-bit non-volatile storage space for user data
■Wide supply voltage range 1.8V-5.5V
■Typical standby power consumption is 0.1μA@3.3V, maximum peak power consumption is 0.45mA@3.3V and average temperature measurement current is 5.2μA (@3.3V, 1 sample per second)
■Every thermometer has a unique ROM ID for easy network addressing
