LoRaWAN temperature and humidity sensor for building monitoring

VISTA FEEL: a LoRaWAN temperature and humidity sensor for buildings

VISTA FEEL combines temperature and relative humidity measurements in one wireless device. This LoRaWAN temperature and humidity sensor helps facilities managers and systems integrators monitor indoor conditions across individual rooms or multiple buildings.

For UK offices, schools, hotels and retrofit projects, readings can be centralised in a monitoring platform or used by a Building Management System (BMS) through compatible infrastructure and interfaces. They provide inputs for comfort monitoring and heating, ventilation or air-conditioning strategies.

Classic or ULL: which version should you choose?

Both versions measure temperature and humidity. The difference presented here is their stated maximum battery life.

Prices above are the GBP prices for UK customers. The product selector displays the active shop currency. Battery life depends on settings and operating conditions and is not guaranteed. Each version uses one replaceable CR123 lithium battery. Select Classic or ULL to see the corresponding price.

A LoRaWAN temperature sensor for indoor comfort

With a stated accuracy of ±0.2 °C, VISTA FEEL works as a LoRaWAN temperature sensor for tracking changes in indoor spaces. Readings help teams compare conditions between rooms and identify differences that need investigating.

In offices, schools and hotels, a LoRaWAN temperature sensor supplies data to facilities teams. Heating and cooling regulation depends on the control equipment and automation installed.

A wireless humidity sensor for indoor monitoring

VISTA FEEL is also a wireless humidity sensor with a stated relative humidity accuracy of ±2% RH. Humidity readings complement temperature measurements to provide a clearer view of room conditions.

Monitoring can highlight changes or periods of high humidity that require further assessment. The sensor does not directly detect mould or determine the cause of a damp problem. Alerts and responses depend on the platform and processes in use.

A wireless temperature and humidity sensor for retrofit projects

This battery-powered wireless temperature and humidity sensor avoids the need to run a power or communications cable to each measurement point. It supports monitoring across several rooms and deployment in existing buildings.

Check sensor placement and radio coverage before installation. For representative measurements, consider heat sources, direct sunlight and the characteristics of the room.

Remote monitoring requires compatible LoRaWAN infrastructure, including a gateway, network server and application platform. NFC is used for local configuration and does not replace that infrastructure.

A temperature sensor for BMS integration

VISTA FEEL can act as a temperature sensor for BMS applications by transmitting readings over LoRaWAN. Integration depends on the gateways, interfaces and building management software installed.

A compatible LoRaWAN-to-BACnet gateway, such as MASTER PRO, allows readings from compatible sensors to be used as BACnet/IP points. Heating, ventilation and air-conditioning scenarios are then configured in the control system.

The sensor supplies measurements. Any energy savings depend on the building, control settings and how the data is used.

L2D1: local communication between NEXELEC devices

The L2D1 radio protocol enables direct exchanges between compatible NEXELEC devices without a gateway or LoRaWAN network for that local communication. This link is separate from the LoRaWAN connection used for remote monitoring.

NFC commissioning and remote firmware updates

Configure VISTA FEEL using NFC on a smartphone with the NEXELEC TOUCH app. Local configuration helps teams prepare sensors on site.

FUOTA V2 firmware updates allow improvements and fixes to be deployed through LoRaWAN infrastructure that supports this function. This reduces the need to visit each device to update its software.

VISTA FEEL: frequently asked questions

What is the difference between VISTA FEEL Classic and ULL?

Classic X420LS offers up to 10 years of battery life. ULL X420LS_ULL offers up to 15 years. These durations depend on settings and use. Both versions measure temperature and humidity.

How accurate are the temperature and humidity readings?

Stated accuracy is ±0.2 °C for temperature and ±2% RH for relative humidity. See the technical documentation for detailed conditions.

Is a gateway needed to view readings remotely?

Yes. Remote monitoring requires compatible LoRaWAN infrastructure. Local L2D1 exchanges between compatible devices can operate without a gateway or LoRaWAN network.

Does this wireless humidity sensor detect mould?

No. It measures relative humidity and temperature. These readings help teams monitor indoor conditions but do not diagnose mould.

Can VISTA FEEL connect to a BMS?

Yes, through compatible infrastructure and interfaces, including a suitable gateway for transferring readings to the building management system.

Does VISTA FEEL measure CO2 or presence?

No. It measures temperature and humidity only. Other VISTA models offer CO2 measurement or presence detection.

Is the battery replaceable?

Yes. VISTA FEEL uses one replaceable CR123 lithium battery. Battery replacement should be included in the maintenance plan.
