Today, we use sensors for a myriad of activities such as intrusion detection, fall detection, patient surveillance, art and goods preservation, offspring care, animal tracking, selective irrigation, and many more. Where the sensor network has to operate outdoors, what can be a better way of powering them other than through solar means?
Using an external or internal solar panel, one can safely recharge batteries for the system. For external solar panels, the panel is usually mounted on a holder Read more [...]
The Internet of Things has led to several simple sensors being used for applications requiring reporting of their readings wirelessly to a gateway or hub. However, most sensors require to be powered from batteries, creating logistical and cost barriers to several use cases. Now, many wireless sensor modules appearing on the market do not require batteries, as they are ultra-low power types.
Several key building blocks are necessary to make up a wireless sensor module meant for IoT use. The first Read more [...]
Industries are increasingly opting for low-power wireless photoelectric sensors with extended range of signals that carry for miles. Such improvements have been made possible with the proliferation of low-power micro-controllers that have boosted the range of the sensors and enhanced their battery life.
In general, wireless sensors conserve and extend battery life by switching themselves off when they are not taking measurements. This allows the sensor to spend most of its time not consuming any Read more [...]
