Reads
• Extreme sensing range from -126.000 °C to 1254 °C
• Accurate temperature readings down to the
thousandths place (+/- 0.002)
• Automatically detects if probe is PT100 or PT1000
• Temperature output in Celsius, Kelvin or Fahrenheit
• On-board data logger storing up to 50 individual
temperature readings
• Optional single point calibration
• Single reading or continuous reading modes
• Data format is ASCII
• Isolation not needed

Two data protocols
• UART asynchronous serial connectivity
• (RX/TX voltage swing 0-VCC)
• I2C (default I2C address 0x66)
• Compatible with any microprocessor that supports
UART, or I2c protocol
• Operating voltage: 3.3V to 5V
• Reads temperature from any off-the-shelf PT100
or PT1000 temperature probe

Sleep mode power consumption
• 0.995mA at 3.3V

Circuit Specs
• Dimensions: 13.97mm X 20.16mm (0.55" X0.79")
• Weight: 1.76 grams
