RuuviTag Pro has an extremely accurate temperature sensor on board. The sensor is designed to meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers. Measurement resolution is 0,01 °C, while absolute accuracy is astounding at ±0,1 °C across the temperature range of –20 to +50 °C, with no calibration.Portable temperature sensor simulators are smaller, easier to transport, and often can run on battery power. They are used for on-site work for checking temperature sensor circuits such as 4-20 mA transmitter systems, oven displays, and PLC (programmable logic controller) systems and are usually optimized for this type of work.Description. The LPS22HB is an ultrapact piezoresistive absolute pressure sensor which functions as a digital output barometer. The deviceprises a sensing element and an IC interface whichmunicates through I 2 C or SPI from the sensing element to the application.The VL53L3CXbines the benefits of a high-performance proximity sensor, with excellent short distance linearity, together with ranging capability up to 5 m. With patented algorithms and ingenious module construction, the VL53L3CX is also able to detect different objects within the field of view (FoV) with depth understanding.
