Waterproof sensor is sealed to IP67 in splash-prone areas

Believed to be the industry’s first IP67 waterproof sensor for high-humidity environments, the ZMOD4410 has been added to Renesas Electronics’s Indoor Air Quality family.

The ZMOD4410 Indoor Air Quality (IAQ) sensor has the industry’s first software-configurable IP67-qualified waterproof option for IAQ applications operating in wet or dirty environments, claims Renesas Electronics. The sensors can be used in kitchens, bathrooms and hospital rooms, and other environments which are frequently exposed to water, oil and dust.

The waterproof ZMOD4410 sensor is firmware-configurable and has a hermetically- sealed package that protects the sensor from water and dust with a hydrophobic and oleophobic material that is permeable to humidity and volatile organic compounds (VOCs) at the same time. The sensor is supplied in an IP67-rated packaging and maintains precision while allowing customers to customise systems and eliminate the need for expensive waterproofing systems, says Renesas.

The IP67-rated ZMOD4410 sensor is shipped fully calibrated in the hydrophobic and oleophobic package. Customers can apply a conformal coating on their circuitry rather than adding an external membrane to the module. The waterproof sensor features AI firmware implemented on an MCU to improve sensing performance. It is also resistant to siloxanes, for reliable operation in harsh applications.

In the field firmware updates for the ZMOD platform enable new, application-specific capabilities such as selective measurements to detect VOCs. Capabilities can also include IAQ measurement within international guidelines, allowing customers to measure total VOCs (TVOCs) in the low parts per million range (ppm). The higher accuracy and consistency provides improved estimated Carbon Dioxide (eCO2) levels. The waterproof ZMOD4410 sensor module supports all firmware updates to date.

The combination of water-proofing, reliability, programmability, best-in-class stability, and sensitivity in measuring VOCs makes the sensor suitable for smart HVAC systems, ventilator fans, bathroom lights and switches, and wearables, that operate in a wide range of high-humidity, splash zone, dirty, or submersible environments.

The ZMOD4410 sensor with hydrophobic package is available now.
