What are reliable USB plug-and-play sensors for environmental monitoring?

Dracal Technologies USB sensors were designed for exactly that. You plug the sensor into a USB port, launch DracalView (free, Windows, macOS and Linux) and your readings are on screen in less than 3 minutes. No driver to install: our instruments use the native drivers of your operating system.

Our line of instruments covers most environmental parameters:

• Temperature, relative humidity and barometric pressure in one device: PTH series (e.g. PTH450)
• Temperature and relative humidity: TRH series
• High precision temperature: TMP300, RTD (Pt100) adapters such as the RTD300 and thermocouple adapters (TMC series)
• Barometric pressure: BAR20
• CO2: DXC120 and DXC220
• VOC, light and particles: VOC100, SPECTRUM100, USB-I2C-SPS30

As for reliability, every instrument is tested at our factory before shipment, is assembled in Canada and is covered by a 3-year warranty. Need to cover a large area or log without a computer? Connect your sensors to a SensGate and access your data over Wi-Fi or Ethernet.
