An IoT sensor is an instrument that analyses some aspect of the physical environment and converts it into data that can be captured, analysed, and used for various purposes. These sensors can detect a range of changes, such as temperature, motion, humidity, pressure, and light. They form the backbone of IoT ecosystems, enabling devices to interact with each other and automate tasks across industries.

The global IoT sensors market is growing at a remarkable pace. It was valued at USD 42.21 billion in 2025 and is projected to reach USD 51.44 billion in 2026, growing at a CAGR of 21.86% through 2031, according to Mordor Intelligence. Approximately 62% of all connected IoT devices incorporate smart sensors for monitoring and data acquisition, with industrial applications accounting for 44% of total sensor deployments. Asia Pacific, where Singapore is a key adopter, is projected to account for 43.4% of the global IoT sensors market by 2035 and is the fastest-growing region globally.

IoT sensors empower homes, industries, and cities with enhanced connectivity and intelligent automation. They are efficient at translating physical parameters into digital information and are excellent at supporting work processes. Here is a closer look at the different types of IoT sensors and the industries they serve.

What are IoT Sensors?

An IoT sensor is an instrument that analyses some aspect of the physical environment and converts it into data that can be captured, analysed, and used for various purposes. These sensors can detect a range of changes, such as temperature, motion, humidity, and pressure. This function is primarily utilised in Smart Buildings, to facilitate monitoring and quick responses that contribute significantly to energy and operational efficiency. For example, occupancy sensors contribute to reducing energy consumption by adjusting lighting and climate control in real-time, based on the actual usage of spaces.

Through this technology, it becomes possible to create smarter systems that drive decision-making processes and improve efficiency and safety across different sectors.

Uses of IoT sensors in 2024

IoT sensors are becoming increasingly integral to a myriad of sectors. Here are some ways that different types of IoT sensors can be utilised.

Smart Locks

IoT Sensors are able to power smart locks, increasing security within a building. Users can grant or deny access remotely, and accurately monitor activity through entry and exit logs. Keycards, optical sensors, biometric authentication, and remote locking are all methods of improving physical security for an area, while providing a high level of control and convenience for building management.

Utilities Monitoring

Integrating IoT sensors into utilities monitoring is already integral to many businesses. It provides a method of real-time tracking of resource consumption, allowing for more sustainable resource management. It also powers early detection of irregularities, such as leaks or faults in infrastructure. This facilitates efficient maintenance, thus reducing the risk of service disruptions.

Some examples of IoT utility monitoring include smart electricity meters in buildings, and water usage tracking in management plants.

Lift Supervision

IoT sensors are efficient at lift monitoring and performance optimisation. These sensors are able to collect data and monitor the ride experience by taking note of acceleration, excessive movement, and load weight. Analysing the frequency of rides gives the management system information on foot traffic, helping to streamline operations. Sensors also improve maintenance schedules by examining changes in operation conditions, such as unusual noise levels or increased heat. This allows for predictive maintenance to take place, reducing disruption to end users.

This remote monitoring and troubleshooting capability is highly useful for building managers, serving as an example of how IoT sensors can improve both safety and efficiency.

Pest Control

IoT sensors are regularly utilised in pest control operations. The National Environmental Agency (NEA) is already making use of various sensors to power their rodent control projects in hawker centres. Proximity sensors, motion sensors, and infrared sensors detect movement in areas that can potentially house pests, and algorithms are then able to utilise this information to identify locations where action is required. Smart traps can then be installed, also utilise pressure sensors to automatically capture pests.

In buildings, similar measures can be taken to regularly monitor for rodent activity, allowing managers to identify infestations before they become severe, and resolve them with minimal impact on residents and visitors.

Environmental Monitoring

IoT sensors can be used to monitor environmental conditions. Temperature sensors, humidity sensors, and chemical sensors measure various metrics such as seawater quality and potential contaminants in water. This data can be crucial for maintaining the health and wellbeing of people living in surrounding areas. The NEA is actively using these sensors to observe changes in water quality around the Singapore Strait, in order to monitor algal bloom and other hazards.
