Technology - Sensors Integration

Sensors play an important role in IoT applications; The Yoswit team has extensive experience in sensor development & integration for a wide variety of embedded devices for IoT applications. Our sensor solutions focus on small size, high accuracy and low power consumption.


Temperature & Humidity

Our solution has the factory-calibrated to 0.2°C temperature accuracy and 2% relative humidity accuracy and includes a heating element to burn away condensation and moisture for increased reliability. The Yoswit selected sensor supports operation from -40°C to 125°C and from 0% to 100% relative humidity.


  • Relative Humidity Range 0% to 100%
  • Humidity Accuracy ±2%
  • Sleep Current 50nA
  • Average Supply Current (1 measurement per second)
    • RH only (11 bit) 300nA
    • RH (11 bit) + Temperature (11 bit) 550nA
  • Temperature Range:
    • Operating: –40°C to 85°C
    • Functional: –40°C to 125°C
  • Temperature Accuracy: ±0.2°C typ.

Power Consumption

We are using single phase multifunction metering chip. We can measure not only the current, but also the voltage and effectiveness of the energy consumption.


  • Indicating active power, meet the accuracy of 50/60Hz IEC 687/1036 standards, in the range of 1000:1 to reach 0.2% accuracy.
  • Can be configured to output current or voltage RMS, in the range of 500:1 to reach of 0.5% accuracy.
  • Built-in power supply monitoring circuit, when the power supply voltage is lower than 4V, the chip will be reset.
  • Built-in 2.43V voltage reference source; 5V power supply, operating current is less than 3mA.

Infrared (IR) Emitter & Receiver

Our solution is capable to with both send and receive in the same IC. It can connect up to 12 emitters at the same time with 15+ meters in range.

We also offer application programming interfaces (API) for various product developers in the Internet of Things and Home Automation market to gain access and interoperability to the world of appliances controlled by 100,000+ infrared codes covering your TV, DVD and speaker, to your fan and air-conditioner..

Lux Sensor

With integrating the lux sensor, which allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from up to 0.1 - 40,000+ Lux on the fly, we can make our lighting solution more intelligent.

Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes). We can separately measure infrared, full-spectrum or human-visible light.

Air Quality

To improve the indoor air quality (IAQ) and promote public awareness of the importance of IAQ, a lot of areas have implemented an IAQ Management Programme. For Yoswit’s solution, we can measure 10 elements out of 11 based on the IAQ Certification Scheme for Offices and Public Places.

  • Room Temperature
  • Relative Humidity
  • Air movement
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Respirable Suspended Particulates (PM10)
  • Nitrogen Dioxide (NO2)
  • Ozone (O3)
  • Formaldehyde (HCHO)
  • Total Volatile Organic Compounds (TVOC)
  • Radon (Rn)
  • Airborne Bacteria


Smart home motion sensors usually form part of a home security kit but can also be used separately to build your own hybrid smart home security system. They are a very effective way of protecting your home and are well worth investing in if you’re looking to bolster your home or small office security.

Combined with the Yoswit Smart Control system, motion sensors integrate into a more complete security setup. For example, you can configure certain motion detectors to turn lights on as you enter a room and off again once you leave. Also, the full history will be tracked in the Yoswit app.
