Renesas Electronics Launches Complete Smart Sensor Solution for IoT Applications

New sensor and signal conditioning ICs complement Renesas’ leading MCU portfolio, advanced firmware, embedded AI, and unique fast-connect IoT design platform

Beijing, China, June 22, 2022 - Renesas Electronics, a global supplier of semiconductor solutions, today announced a series of new solutions to change the way designers build sensor-connected IoT applications, thereby shortening design cycles, improving accuracy, and reducing system costs.

In addition to the new HS4XXX family of relative humidity and temperature sensors, Renesas also released the ZSSC3281 sensor signal conditioning (SSC) IC, which is used to amplify, digitize, and calibrate sensor signals with high precision. The new products complement Renesas' extensive MCU portfolio and embedded AI solutions.

All of these products are supported by Renesas' unique system design platform, which significantly simplifies the prototyping of IoT systems. Renesas' Quick-Connect IoT system consists of standardized boards and interfaces, allowing designers to quickly and easily connect a variety of sensors to MCU/MPU development boards. The new system also provides core software building blocks that can be ported between boards, greatly reducing programming requirements. Now, instead of writing and debugging hundreds of lines of driver code, designers only need to graphically select sensors and write a small amount of code. All integration and setup work is done behind the scenes, shortening the time to get a usable solution.

Renesas has also created a number of "winning product combinations" that combine sensors with multiple other ICs to build an advanced design platform for users to reduce design risks and shorten development time.

According to a recent study by Zion Market Research, the global IoT sensor market is expected to expand at a compound annual growth rate (CAGR) of approximately 27.9%, reaching a market size of $27.9 billion in 2028.

“Sensing solutions are a critical element in IoT systems, but they also present many design challenges during system integration that can slow down development and impact overall system performance,” said DK Singh, Senior Director of the System and Solutions Business Unit at Renesas Electronics. “Renesas’ fusion of sensor technology, signal conditioning expertise, and system solution thinking enables us to build a competitive, superior design platform for our customers.”

With more than 20 years of experience, Renesas has deep and broad expertise in the sensor market. Renesas' product portfolio includes sensor signal conditioners, biosensors, humidity and temperature sensors, light and proximity sensors, flow sensors, and position sensors.
