Here is another guide working with the HDC2080 high accuracy digital temperature & humidity sensor developed by Texas Instruments. The HDC2080 is an integrated humidity/temperature sensor the provides a high accuracy sensing acquisition with very low power consumption in a DFN – (Dual-flat no-leads)package featuring a new integrated digital heating element to dissipate the condensation moisture.
This sensor communicates on a two-wire protocol (i2C) and includes programmable interrupt thresholds that provide alerts and system wakeups without requiring input from the microcontroller to be continuously monitoring the system. Combines with deep sleep mode and programmable sampling intervals with low power consumption that supports a 1.8v supply voltage that suitable for a handheld device that runs on a battery-powered project.
HDC2080 provides you a high accuracy in terms proving a temperature and humidity suitable for smart environmental monitoring or an IOT project application such as smart appliance that monitors temperature, smart thermostats, smart home assistants, smart device’s specific applications, and mobile devices.
If your searching for an auto measurement sensor the strict the power-budget the HDC2080 is suited your requirements. For more technical details please refer to the datasheet below.
