New Thermopile-Based Detectors from Renesas

Renesas Electronics has expanded its environmental sensor portfolio with four new single- and dual-channel analog detectors (RH5Z0610D, RH5Z0622D, RH5Z1210D, and RH5Z1222D) for carbon dioxide gas. Delivering high performance, quality, and longevity in a TO-5 package, these detectors are ideal to be used in a variety of industrial, medical and IoT applications that require high reliability, high accuracy and operation in high temperatures.  

These new thermopile-based detectors deliver fast response times with a time constant ranging from 18 to 25 ms and a high signal-to-noise ratio ranging from 1,981 to 4,953 offering high accuracy required for mission-critical applications where high reliability is required.  Supporting applications operating with extended temperature ranges up to 125°C, these devices are certified for high temperature environments.

The customers can combine these new detectors with popular sensors from Renesas such as ZMOD4410 IAQ platform featuring embedded AI and an IP67-rating package option, and/or HS3001 high-performance, highly accurate relative humidity and temperature sensor to create a complete environmental sensing solution for medical or industrial applications.

Additionally, the new thermopile-based detectors are combined with the complementary analog and power devices and Dialog’s Bluetooth Low Energy system on chip to create the new Thermopile CO2 Detector Winning Combination to detect ambient CO2 concentrations.  As far as the availability is concerned, the RH5Z0610D, RH5Z0622D, RH5Z1210D, and RH5Z1222D thermopile detectors and thermopile detector evaluation kit is available now from Renesas’ worldwide distributors.
