– Global positioning system tag – communicates with GPS satellites to establish position with high accuracy, but only when the tag or animal is on land or at the water surface – Fastloc Global positioning system tag – GPS tag for aquatic animals that surface or haul out, when the tag locks onto the GPS satellite network to establish position with high accuracy – Pop-up satellite archival tag – after some period of time recording sensor data, the tag detaches itself from the animal and floats to the surface where it uses satellite connectivity to uplink the data stored on the tag – Acoustic tag – attached to the animals being tracked emit acoustic signals (typically ultrasound) which travel through water much better than RF signals. These signals are then received by buoys, which can then use satellite communications to backhaul the data to where it’s needed.
* Temperature & humidity sensors * Volumetric airflow & fluid sensors * Mold sensors * Occupancy detecting sensors * CO2 demand-controlled ventilation (DCV) sensors – work with sensors that detect a building’s occupancy and adjust ventilation accordingly * Light Sensors tied to motorized window treatments can pick up on sunlight and adjust window shading during the course of a day

Portable waste bin or portable toilets enabled with GNSS. Once data related to fill rates and temperatures of smart bins /toilets are collected, the sensors relay the exact location and other waste related information of the bins in question so waste management can send out SMSes to nearby garbage collectors to do the needed collection/emptying before harmful carbon emissions are released.
RFID Readers: E.g., Handheld Typical uses: Warehouses: Tracking assets that are packaged or inside a container Hospitals: Tracking asset locations automatically within a limited distance range

soil moisture sensors – used to assess the water level in the soil temperature and humidity sensors – used to monitor the environment, which had a direct influence on the water level of the soil
Some of the key types of sensors used in urban air quality monitoring include: Particulate Matter (PM) Sensors: These sensors measure concentrations of particulate matter Nitrogen Dioxide (NO2) Sensors: NO2 is a common urban pollutant, often produced by vehicle exhaust and industrial processes. Sulfur Dioxide (SO2) Sensors: Commonly produced by industrial processes, SO2 levels are often monitored using ultraviolet fluorescence or electrochemical sensors. Ozone (O3) Sensors: Ozone at ground level is a harmful pollutant, and its concentration is typically monitored using ultraviolet (UV) photometry or electrochemical cells. Carbon Monoxide (CO) Sensors: CO is a colorless, odorless gas resulting from incomplete combustion. It’s usually monitored in urban environments using electrochemical sensors. Volatile Organic Compounds (VOCs) Sensors: VOCs are emitted from a variety of sources, including vehicle exhaust, industrial processes, and consumer products. Meteorological Sensors: These sensors measure environmental conditions like temperature, humidity, wind speed, and wind direction, which are important for understanding and interpreting air quality data.
Tag sensors and readers for tracking people, collecting environmental data, equipment tracking, and real-time alerts. RFID transmitter devices are mounted on headlamps belts or badge cards of miners to enable tracking of workers in real-time.
The rodent sensors are placed in the high rodent-activity areas for inspection. When rodents pass through the location, infrared sensors trigger notification to all the relevant parties such as owner and pest management service about the rodent activity so that they can decide a plan of action of elimination.
UAV generally carries a video camera and other sensors such as laser scanner, GNSS, gyroscope,accelerometer, and barometer. Streaming the video and other sensor data to a remote location for instant storage, verification and analysis allows the survey team to gauge whether additional data needs to be collected.
Underground mining has significant safety hazards due to high-stress concentrations, weak rock masses, and limited access and air quality. Different sensors are used in mine-related activities, such as geophones in exploration and blast control, piezometers in dewatering and toxic gas detectors in working frontlines.
Wind Sensors (Anemometers): measure wind speed and direction, key factors in sandstorm formation. By understanding wind patterns, it becomes easier to predict the movement and intensity of sandstorms.
Wireless Z-Traps are devices used to catch pests around the plants using pheromone lure. Pest count information is wirelessly passed along from up to 1 km away using a base station to the online cloud service. This information is used to study and determine where and how much pesticides will be required. Imagery sensors capture imagery data to identify the diseases in plants – RGB sensors – have three colour channels, i.e., red, green and blue, which can be used to perceive the biometric effect in the plants – fluorescence Imagery sensors – used to distinguish the photosynthetic activities in the plants – spectral sensors – capture images containing the spatial information of objects in multiple wavebands, used to analyse crops’ health and pest attack – thermal sensors – used to measure the water status in the plant by measuring the temperature Weather condition monitoring sensors, i.e., temperature, dew, humidity and wind speed, are used to monitor weather parameters to find a correlation between pest growth with weather
