Overview

Temperature sensors are mounted in various locations in industrial equipment and measurement results are output through visual display and communication functions. Measured sensing data is utilized to control the operating environment of the equipment and the process temperature, etc.

Renesas offers a wide range of products, from microcontrollers with built-in analog front-ends required for temperature measurement, general-purpose microcontrollers for main control with communication and display functions, to drivers for communication with high-end equipment and peripheral parts.

The HS3001 is a temperature-compensated calibrated I2C output temperature humidity sensor. It can measure stably with high speed and high accuracy.
