“In this project, we build an economical and full-featured Bluetooth Low Energy (BLE) data logging system that takes readings from multiple sensors and saves the data to an SD memory card. A data logger is an integral part of environmental …
Content for TMP007
The TMPOO7 is an infrared (IR) thermopile sensor that measures the temperature of an object without contacting the object. The integrated thermopile absorbs the infrared energy emitted from the object in the sensor field of view. The thermopile voltage is digitized and provided as an input to the integrated math engine, along with the die temperature (Tpg). The math engine then computes the corresponding object temperature. Default calibration and thermal transient coefficients are stored in the built-in nonvolatile EPROM memory. Application specific values can be stored for improved accuracy. An alert function is available, and can be programmed in either comparator or interrupt mode. The TMP007 is compatible with 1°C and SMBus interfaces, and allows up to eight devices on one bus. Low power consumption along with low operating voltage is ideal for battery-powered applications. The TMPOO7 provides convenient, noncontact thermal solutions for measuring temperature with factory-supplied calibration. This device is also suitable for industrial and consumer applications with a user-customized system calibration.
