Tiny smart waste sensor cuts emissions significantly

-

 OSCAR from adhoc networks is the world’s smallest, smart, waste sensor module, measuring a mere 71- x 43- x 28-mm. The optics can measure up to 4m within a container with a cone angle of 27° to determine the fill level. The company’s waste sensor modules are the key to its automated, fill-level detection and collection scheduling technology for local authorities and private companies that can reduce unnecessary collection trips to containers that are only partly filled.               

The optical sensor in the device monitors the fill level in the waste container and sends that data for centralised processing to enable a schedule of waste collection to be created. Because waste is only collected when the containers are actually full, CO2 emissions by the collection fleet can be reduced by up to 40%.

“Knowing the exact level in every container ensures that there are no wasted collections of part filled containers and, even more importantly, no overflowing containers,” explained Ole Ostermann, adhoc networks’ CEO. “Our approach is the perfect solution for monitoring the new generation of waste containers that are larger and discretely located below ground level. These are not currently easy to check the fill level apart from lifting a lid so they are usually emptied more often than necessary just to be sure, but that is a waste of resources.”

The OSCAR waste sensor uses a Nordic Semiconductors’ nRF9160 SiP to collate data and send it to the Cloud over the mobile network LTE-M and Narrowband-IoT. It has a low power need so its 3.6-V Li-Thionyl Chloride battery has an operational life of up to five years based on, typically, twelve fill measurements a day and three uplinks of the data to the Cloud.

  STMicro Unveils 6-axis IMU with Embedded Sensor Fusion and AI Among the most fundamental trends in the consumer electronics industry today is the proliferation of sensors . For applications such the Internet of Things (IoT), wearables, and AR/VR, sensing has been a core technology. As devices become embedded with more and more sensors , system developers face about how to best handle and fuse that data into a useful format. To address this issue,  STMicroelectronics (ST) has recently released  a new 6-axis IMU which includes a number of integrated features such as sensor fusion blocks and Machine Learning (ML) cores.   1st Editional of International Research Awards on Sensing Technology | 23-24 Jan 2023 | India Abstract Submission:  https://x-i.me/gaycon Award Nomination:  https://x-i.me/gaynom Member Nomination:  https://x-i.me/gaymem Visit:http://sensors-conferences.sciencefather.com/ For Enquiries: sensors@sciencefather.com

Temperature Sensors

  Temperature Sensors: A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record, monitor, or signal temperature changes. There are many different types of temperature sensors. Some temperature sensors require   direct contact   with the physical object that is being monitored (contact temperature sensors), while others indirectly measure the temperature of an object (non-contact temperature sensors).   Non-contact temperature sensors are usually infrared (IR) sensors. They remotely detect the IR energy emitted by an object and send a signal to a calibrated electronic circuit that determines the object's temperature. Among the contact temperature sensors are  thermocouples and thermistors . A thermocouple is comprised of two conductors, each made of a different type of metal, that  are joined at an end  to ...

  What are Sensors, Detectors, and Transducers? Sensor/Detectors/Transducers are electrical, opto-electrical , or electronic devices composed of specialty electronics or otherwise sensitive materials , for determining if there is a presence of a particular entity or function. Many types of sensors , detectors, and transducers are available including those for detecting a physical presence such as flame , metals , leaks , levels, or gas and chemicals , among others. Some are designed to sense physical properties such as temperature, pressure, or radiation , while others can detect motion or proximity . They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others. Many applications over a wide range of industries use sensors, detectors, and transducers of many kinds to test, measure, and control various processes and machine functions. With the advent of the  Internet of Things (IoT) , the need for sensors...
