After a decade of bio-materials engineering research at U.C. Berkeley and Lawrence Berkeley National Laboratory, Calyx was spun out with the mission to apply advanced bio-materials to low-cost power-efficient sensors for the detection and characterization of airborne chemical compounds.

Calyx has patented a whole new paradigm in sensors, using engineered proteins to detect gases. Our bio-sensors are accurate and durable, and can detect a wide variety of compounds. While receiving interest from various industries, we are now focusing on providing an integrated solution to environmental management in the animal farming industry.  

Though animal farming will be our beachhead market for the next 18~24 months, long-term, our roadmap foresees BioMEMS sensors providing solutions to numerous consumer and industry problems.


  • Y-series
    Y-series is your go-to solution for a fully integrated ammonia sensing system. It is wireless and can operate on battery power for multiple years with minimal calibration maintenance from sub-freezing to 50°C....

  • Calyx’s Y-series is a fully integrated system with wireless transmission capability and provides the optimal price to performance metric to operate in any situation. Y-series can be powered via batteries or 3.6~5 VDC power, analyzes ammonia in real-time and transmits the data wirelessly using LPWAN technology.

    Highlights of Y-series include:

    • Long Operating Life: Y-series can operate for multiple years on battery power with minimal maintenance such as an occasional calibration check
    • Fast Response: the sensor rapidly responds to concentration changes, with a T90 under 60 seconds
    • No Drift: the sensor operates normally in the continuous presence of ammonia
    • Configurable: the operator can choose a wide variety of parameters, such as sampling period, transmission period, and power options.

    Features on Y-series:

    • LED indicator for operation status, updates, and alarms
    • Wireless transmission
    • Optional power supply between battery pack or DC power
    • Allows factory and user setting restoration in case parameters are lost accidentally
    • Transmit setup information and battery voltage to a wireless receiver
    • Extended hub for future sensor add-ons
    • The long-lasting operation, regardless of the environment
    • Alternative mount options available
    • Lower detection range option available
    • Extended temperature range available
    • Rapidly responds to changes in ammonia concentration with a T90 of under 60 seconds
    • Operators can adjust a wide variety of parameters
    • Operators and managers can use Calyx Cloud Service Platform to monitor the environmental concentration change in real-time
    • Conveniently replace and change to different industry detection needs
    • No calibration is required

    Operating a Y-series is as simple as putting the sensor in the desired location and turning it on. It gives accurate ammonia readings continuously and automatically.
