You should consider ROI-RFX Wireless Temperature Monitoring System. LR WPAN Thermistor input 2.4GHz IEEE 802.15.4 modules. Because they let you use thermistors with wireless connection for temperature measurement.
Wireless Temperature Monitoring System
The ROI-RFX is a versatile 2.4GHz wireless input module. It is a Wireless Temperature Monitoring System LR WPAN (Low-Rate Wireless Personal Area Network) device utilizing IEEE standard 802.15.4 protocol.
The ROI-RFX is a versatile because a signal range is available for many sensor measurement applications, as well as serial input if needed. The supply voltage range is a wide 7 to 36Vdc. As well it is compatible with a number of software options.
When you have nearby temperature measurements you need to make, but inconvenient or too difficult for a direct wire connection, and need to add temperature measurement, use ROI-RFX series thermistor input modules. Because ROI-RFX series thermistor input modules allow the simple measurement of industry standard 10K NTC thermistors. So you can easily connect your existing thermistors to a modern environmental system. They are a simpler way to add thermistor measurement than other types. Thermistors are simpler to use than other temperature sensors. Because thermistors are easy to install, and just use standard copper cable, they are useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and a variety of other applications.
Simple to use wireless temperature measurement
When you need simple to use wireless temperature measurement, use the ROI-RFX series. In other words ROI-RFX series wireless thermistor input modules are a simple way to add thermistor measurement to an environmental monitoring system.
Useful because it provides wireless temperature sensing, for remote temperature monitoring over distances up to 1 mile using industry standard 10K ohm NTC thermistors
Because the ROI-RFX-RT is a simple to use Windows compatible 2.4 GHz RF wireless remote temperature transmitter system. Firstly, using the ROI-RFX-RT allows you to remotely monitor & record temperature over distances of up to 1 mile/1.6 km. Secondly it uses industry standard 10K ohm NTC thermistors. Therefore, remote temperature measurement or temperature profile recording is simple; data can be updated real time directly into Excel, on custom screens, recorded to file, and more! Total transmission distance can be extended with additional units, as well as allowing an increased number of sensors.
So you can, monitor 4 thermistor temperature sensors per unit. Multiple units per system, expandable as needed.
