Makes it easy to monitor four measurements with one versatile logger. The kit includes the HOBO MX1104 logger with integrated sensors for temperature, humidity, and light, plus an external temperature sensor with a 6' cable. This is a great addition to your toolbox for troubleshooting, equipment scheduling, building commissioning, HVAC performance monitoring, and more! The external input provides the flexibility to connect a wide range of sensors, expanding monitoring capabilities.
The self-contained 4-channel logger leverages Bluetooth technology for easy wireless configuration and data offload using Onset's free HOBOconnect app for mobile devices and Windows computers. The 100' wireless range is especially handy when deploying these loggers in hard-to-access locations. And, if used with the MX Gateway, you can access data in Onset's cloud-based HOBOlink software - from anywhere!
