Renesas Electronics Corporation is changing the way designers build sensor-connected IoT applications with a range of new solutions targeted at faster design cycles, improved accuracy, and reduced system cost.
In addition to the new HS4XXX family of relative humidity and temperature sensors, Renesas is introducing the ZSSC3281 sensor signal conditioning (SSC) IC for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. These new products complement Renesas’ extensive MCU portfolio and embedded AI solutions.
The sensor design process is supported by Renesas’ unique system design platform that significantly eases the prototyping of IoT systems. The Renesas Quick-Connect IoT system consists of standardized boards and interfaces, enabling designers to quickly and easily connect a wide range of sensors to MCU/MPU development boards. The new system also delivers core software building blocks that are portable between boards, greatly reducing coding requirements. Now, instead of writing and testing hundreds of lines of driver code, designers only need to graphically select their sensor and write a few lines of code. All the integration and setup efforts happen behind the scenes, reducing the time to a working solution.
Renesas also provides numerous Winning Combinations that combine sensors with multiple other ICs to offer customers an elevated design platform that mitigates the design risks and reduces development time.
According to a recent Zion Market Research study, the global IoT sensors market is estimated to grow at a compound annual growth rate (CAGR) of approximately 27.9%, reaching an estimated $27.9 billion by the year 2028.
With more than 20 years of experience, Renesas has deep and broad expertise in the sensor market. Renesas’ portfolio includes sensor signal conditioners, biosensors, humidity and temperature sensors, light and proximity sensors, flow sensors, and position sensors.
The new HS4XXX family of relative humidity and temperature sensors provides high accuracy, fast measurement response time, and ultra-low power consumption in small package sizes, making them ideal for a wide number of applications ranging from portable devices to products designed for harsh environments.
