What is a wireless temperature sensor, and how does it work?

A wireless temperature sensor is a small, unwired device for measuring and monitoring temperature. The remote temperature sensor sends data to a nearby gateway, which transmits the data to the cloud.

El-Watch’s IoT temperature sensors stay connected via 2G/4G, measure temperatures every three seconds, and store reports every two minutes. Critical anomalies are immediately reported. The integrated battery has a 10-year lifespan, and all monitoring is available in our Neuron sensor app.

We offer over 50 different sensor types. Explore the possibilities in our product brochure.

Types of wireless temperature sensors

Temperature sensors are commonly divided into two categories: Contact type and non-contact-type temperature sensors. The former measures heat by direct contact, while the latter detects infrared radiation (IR) emitted from a heat source.

Thermocouple (TC) vs. Resistance temperature devices (RTD)

Contact temperature sensors are constructed in many ways, inflicting how they perform, how they age, and what they cost. The most popular industrial sensor types are thermocouples (i.e., type K ) and resistance temperature devices (i.e., PT100 ). The first one is cheaper and can measure very high temperatures, while the latter is more accurate and repeatable.

The Neuron PT100 is designed to be connected to a PT100-element and will transfer the measured temperature to the Neuron Cloud.

Infrared radiation temperature sensors (IR Sensors)

Non-contact sensors are electronic devices that convert heat radiation to electric signals. They are sensitive to infrared radiation from all heated physical objects; the hotter the surface, the stronger the radiation. When the surface gets really hot, we can see the radiation with our own eyes as a red or yellow glow.

The Neuron Infrared 380 sensor measures surface temperature on the object it is directed towards. It is designed for industrial temperature measurements, capable of measuring up to 380°C.

What are wireless temperature sensors used for?

Many industries use wireless temperature sensors to keep equipment and environments at optimal functionality. El-Watch’s customers commonly use IoT temperature sensors for a wide range of purposes.

Building automation

Centralized building automation reduces energy consumption and operating costs and improves systems operations and equipment lifecycles. IoT sensors are a vital part of this since they enable remote temperature control.

HVAC

HVAC (heating, ventilation, and air conditioning) naturally connects to building automation but extends to all kinds of closed spaces. Factories, greenhouses, and the food industry commonly use remote temperature sensors for HVAC.

Food safety

Both transport and storage of fresh foods come with strict safety regulations. The temperature must never drop below certain limits, and food safety authorities require documentation of temperature upkeep from slaughterhouses to stores and restaurants. For this purpose, wireless temperature monitoring is indispensable.

Indoor farming

Indoor farming is taking off these days. Container farming, greenhouse cultivation, and vertical farming are becoming recognized industries around the globe. They all rely on temperature monitoring, and most of them utilize IoT temperature sensors.

Industry enhancement

Smart temperature sensors enable predictive maintenance in a wide range of industries. Any moving parts prone to wear and tear will need maintenance or replacement. Wireless temperature sensors let companies know how hard they can push their equipment and when to plan maintenance to minimize expenses.

Server room optimization

Keeping server rooms cool is vital to ensuring the safe storage of data, keeping energy consumption low, and limiting environmental impact. Remote temperature sensors are used to make sure that server rooms always operate at maximum capacity.

Examples of wireless temperature sensor industrial applications

Now you have a good idea of wireless temperature sensors’ many purposes. Let’s take a look at a few real-life examples of sensor applications. First, we’ll return to the food industry and a small local venison producer.

Venison producer saved by wireless IoT sensors

This venison producer on the western coast of Norway had installed IoT temperature sensors to document temperature levels. The temperature monitoring saved them from trouble with the food safety authorities. The open-closed sensor kept all their meat from spoiling when they accidentally left the freezer door open.

Vertical farming grows big with myriads of temperature sensors

Plant factories are popping up around the globe, and remote temperature sensors are integral to their success. The Norwegian plant factory supplier Avisomo uses copious amounts of IoT sensors. This helps their clients attain optimal plant growth, lessen the workforce, and promote sustainable food production.

HVAC improved in office building; energy went down by 35 percent

Top 10 benefits of wireless temperature sensors

In sum, these are the ten best reasons why wireless sensors are worth the investment!

1. Remote systems management

The ability to monitor and adjust system temperatures on the go is priceless. IoT temperature sensors give you total control to track and correct operations from your PC, laptop, or smartphone.

2. Increased productivity

Predictive maintenance makes you aware of how hard you can push your machines without damaging their structural integrity. This has proven to increase productivity in all kinds of industries.

3. Lowered maintenance expenses

Predictive maintenance also enables you to strategically plan your system upkeep and upgrades so that productivity standstills are kept at a minimum.

4. Immediate notice of anomalies

Should temperature anomalies occur, an alarm will set off push notifications. These will immediately appear on your app or be sent by e-mail or SMS.

5. Removal of repeated mistakes

The large amount of data collected makes it easy to analyze and pinpoint the origins of anomalies and mishaps. Once the source is determined, the cause can be eliminated to avoid similar accidents.

6. Lowered energy consumption

Temperature monitoring is especially advantageous in large industries. Accurate temperature optimization according to weather conditions and off-hours, for instance, has considerably lowered energy consumption in many industries.

7. More sustainable operations

Energy savings also makes your company more sustainable. This point should perhaps come first on our list since wasted energy on poor temperature control is an issue that concerns us all.

8. Easy adherence to compliance requirements

Food safety regulations are the prime example since most food safety authorities require documentation of an unbroken cold chain from producer to seller. IoT temperature sensors and monitoring make compliance a breeze.

9. Better control of company finances

IoT monitoring is designed to streamline industry operations and systems management. The result is fewer unexpected problems and steadier production, which means more predictable financial projections.

10. Promotes digital transformation

Steering your company towards digital transformation means restructuring your priorities and repurposing your resources for maximized return on investment. Digitalized temperature monitoring promotes smooth systems operation so that you can focus on constructive development and business expansion.
