Wireless Weight Scale | Renesas
Whether you are trying to measure ounces to thousands of pounds this flexible design covers them all. The sensor signal conditioner has a programmable, integrated sensor front-end allowing designers to apply various sensors for a broad range of applications. The Bluetooth® Low Energy (LE) allows use in applications where a wired interface cannot be used. And, weight can be displayed on any Bluetooth-connected screen. System Benefits:
Simple and highly flexible design
Weight range is based on the strain gauge used
System in low power mode when not measuring
System wakes up with GUI prompt
Target Applications:
Portable consumer, industrial, vehicle, commercial weight scales
Connected scale for health and fitness apps
Flexible to meet many applications

Indoor Air Quality Sensor Platform
The ZMOD4410 Gas Sensor Module is designed for detecting total volatile organic compounds (TVOCs) and monitoring indoor air quality (IAQ). It is a 12-pin LGA assembly (3.0mm x 3.0mm x 0.7mm) that consists of a gas sense element and a CMOS signal conditioning IC. An additional package supporting a waterproof IP67 rating is also available (3.0mm x 3.0mm x 0.9mm). The module’s sense element consists of a heater element on a Si-based MEMS structure and a metal oxide (MOx) chemiresistor. The signal conditioner controls the sensor temperature and measures the MOx conductivity, which is a function of the gas concentration.
The measurement results can be read via an I2C interface with the user’s microprocessor, which processes the data to determine the TVOC concentration, IAQ rating and estimated carbon dioxide (eCO2) level. This flexibility makes the sensors in the ZMOD4410 platform capable of providing a variety of measurement options by varying the method of operation or changing the firmware used to interpret the resistance measurements. Downloadable firmware libraries and source code provided by Renesas enable detection of TVOCs and odors and support smart devices measuring IAQ that require low-power operation. The ZMOD4410 is ideal for applications such as thermostats, air purifiers, building controls, smart fans, HVAC equipment, and smart devices.
