Sustainable, Earth-friendly Current Sensor for Reduction of CO2 Emission
Currentier current sensors are well-suited for the control of Inverter Air Conditioners. The increased adoption of inverter-controlled air conditioning systems as a whole helps to reduce the emission of greenhouse gases.
Currentier has been designed in by the world’s top HVAC vendors. Using Currentier to measure inverter current allows vendors to precisely control the inverter, shorten the product development cycle, and miniaturize the system.
The primary conductor resistance of CZ37xx can be as low as 0.27 mΩ. This greatly reduces heat generation due to high current, as compared to the use of shunt resistors or similar devices from other companies. The small, thin surface mount package and small number of required peripheral components enable a flexible layout. Both creepage and clearance are greater than 8 mm, in compliance with UL61800-5-1 and certified with UL62368 and UL1577. In addition, New Chip, fast response, high accuracy current sensor with a higher current capability of 100Arms, was introduced.
Ultra-Low Power CO2 sensor : Sunlight CO2
The world's most power-efficient NDIR CO2 sensor, optimal for battery and wireless applications. ANSI / ASHRAE 62.1-2022, RESET grad B and WELL Building Standard ® compliant.
* WELL Building Standard ® is a registered trademark of the International WELL Building Institute (IWBI), a U.S. public benefit corporation, in the United States and other countries.
Flammable Gas sensor : Sunlight R32
The world's most efficient refrigerant leakage detector, increasingly a requirement in air conditioners, particularly in the North American market. IEC standard 60079-29-1 and IEC 60335-2-40, and UL 60335-2-40 compliant.
Wireless CO2 sensor beacon
Maintenance-free operation with a single coin-cell battery for more than a year. This is an introduction to the reference design support of a modular "CO₂ Sensor Beacon" that can be operated with a single coin-cell battery using a Senseair CO₂ sensor Senseair. By using the application note, schematic, BOM, Gerber files, receiver software, etc., modular designs can be advanced quickly.
Demonstration at AHR2023
