Wireless Sensor for Temperature, Humidity, CO2, TVOC, & Pressure

A good indoor environment promotes comfort, preserves health, and safeguards property value. Optimal indoor air quality enhances the well-being of occupants and work productivity.

The Kombi-Sky cost-effective wireless multi-sensor indoor air quality transmitter addresses these needs. Kombi-Sky measures temperature, humidity, carbon dioxide (CO2) levels, total volatile organic compound (TVOC) levels, and differential pressure.

Operating on LoRa technology, the battery-powered air quality sensor offers extensive wireless coverage without the need for constant attention post-installation or parameter configuration.

It’s worth noting that this Sky radio device is not compatible with the LoRaWAN infrastructure. If LoRaWAN compatibility is required, the Kombi-LWEU model is the recommended choice.

Indoor Air Quality Transmitter Measurements

The device’s operational temperature spans from -30 to +60 °C, while its storage temperature range is -40 to +80 °C (non-condensing) when the device does not have radiators. The indoor air quality transmitter carries a protection class rating of IP20 and is constructed with a plastic housing (ABS+PC).

The Sky radio antenna operates within a frequency range of 433.05 to 434.79 MHz and can transmit with a maximum power of 10 dBm ERP, providing an open space range of about 10 km under optimal parameters.

It is powered by 3 AA 1.5 V alkaline batteries, with a typical battery life of three years at a 30-minute transmission interval. Alternatively, it can be powered externally via Micro USB type B with 5 ± 0.5 V and a maximum current of 200 mA.

Regarding its measuring ranges and accuracies:

Temperature:
- Measuring range: -40 to +125°C
- Accuracy: ±0.1°C (+20 to +60 °C)
Moisture:
- Measuring range: 0 to 100 %RH
- Accuracy: ±2 %RH (+0 to +80°C, 0 to 100 %RH)
CO2:
- Measuring range: 400 to 5000 ppm
- Accuracy: ±45 ppm + 3% rdg
TVOC:
- Measuring range: 0.3 to 30 ppm
- Accuracy: ±15%
Pressure Difference:
- Measuring range: -125 to +125 Pa
- Accuracy: ±0.08 Pa + 3% rdg

The device, including its batteries, has a weight of approximately 210 grams, and its dimensions measure 75 mm in width, 48 mm in height, and 105 mm in depth.
