Smoke Sensors

They have been in use for a long time but their integration with the IOT industrial automation solutions has created some interesting use-cases.
These sensors find widespread use in applications like HVAC, construction site monitoring and the industrial units where a chance of fire and gas leakage is on a higher side.
When smoke sensors are integrated with an industrial IoT solution, even the slightest leakage of gas or minor occurrence of fire can be reported to the concerned team and major disaster can be averted.
Companies like Heiman and Nest Protect manufacture smart IoT smoke sensors for both home and industry applications. These Zigbee or WiFi enabled sensors cost anything between $2 to $10 depending on the quality.

Proximity Sensors

As the name suggests, these sensors measure the distance from itself and the nearest object. They are most commonly found on the car bumpers to alert the drivers in the case of an imminent collision.
Proximity sensors also find application in the retail industry where the customer is informed about the discount as he or she walks near a product.
Other use cases are assembly lines of different industries like food, chemical, machine tools and many others.

Infrared Sensors

Infrared sensors are essentially used to detect human presence.
Infrared sensors have been deployed for Military applications extensively but over the few years, IR sensors integrated with the industrial IoT solution are finding applications in other industries as well.
As these sensors can detect any infrared radiation including heat, they are deployed in electronics, chemical, and healthcare industries to name a few.
Asahi Kasei Microdevices (AKM), Murata, Melexis MLX90614, Intersil ISL29021 are among the few IOT IR sensors used in Industries.

Piezo Sensors

The piezo sensors measure pressure and when integrated with an IoT solution can send data related to pressure changes in real time.
Using these sensors, we can develop an industrial IoT system that is capable of monitoring pressure in pressure-critical equipments such as boilers, water systems, aerospace, oil drilling systems and more.
Pressure Systems Series 960, 970, Paroscientific Inc. Series 1000, 2000, 6000, Environdata BP10 Series are some of the most commonly used pressure sensors in industrial IoT applications.

Temperature Sensors

Temperature sensors are among the most widely used sensors in industrial IoT applications.
They find their use-cases in numerous industries that include FMCG, pharmaceuticals, biotechnology, and others where temperature-monitoring is crucial.
Melexis MLX90614, Environdata TA40 Series, Geokon 4700 are the top picks for temperature sensors in industrial IoT applications.

Optical Sensors

Optical sensors are one of those sensors that are capable of sensing more than just light.
The underlying technology of these sensors lets it monitor any kind of electromagnetic radiation, i.e. light, electricity, and a magnetic field etc.
Telecom, elevators, construction, healthcare, safety systems are some of the Industrial automation applications of Optical Sensors.
Vishay’s VCNL4020X01 and TCxT1600X01 are optical sensors designed specifically for the industrial IoT applications.

Image Sensors

Image sensing has the power to revolutionize industrial automation in lot of industries like healthcare, transportation, and more.
When integrated with the Internet of Things (IoT) enabled system, these sensors can help in monitoring of hospitals, factories, and more.
These sensors can measure blood pressure with every beat, read the variation in pressure over the entire day and help in the prevention of cardiovascular diseases.
In the transport sector, image sensors can help prevent train collision by alerting the driver of an approaching train on the same track..
Omron and Invisage are two pioneers who are implementing the image sensing technologies in IoT with great outcomes.
