SEN-15805 High Precision Temperature Sensor SparkFun SEN-15805 High Precision Temperature Sensor outputs temperature readings with high precision of ±0.1°C, across the temperature range of -20°C to +50°C, with no calibration and a maximum range from -55°C to +150°C. The SEN-15805 Sensor has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. The SEN-15805 utilizes the Qwiic system with no soldering required.
