New Sensors and Signal Conditioning ICs with Advanced Firmware and Embedded AI for IoT Applications

Renesas's Sensors and Signal Conditioning ICs

Renesas Electronics Corporation has introduced the new HS4XXX family of relative humidity and temperature sensors along with the new ZSSC3281 sensor signal conditioning (SSC) IC designed for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. The sensor design process is supported by Renesas’ unique system design platform that significantly eases the prototyping of IoT systems.

The new ZSSC3281 SSC is suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors powered by an on-chip current source. It includes a two-channel analog front end as well as an integrated ARM-based MCU with embedded mathematics for sensor signal processing and targets high-end applications including industrial, medical and consumer sensing. 

The new HS4XXX family of relative humidity and temperature sensors provides high accuracy, fast measurement response time, and ultra-low power consumption in a small package size, making them ideal for a wide number of applications ranging from portable devices to products designed for harsh environments.
