IR technology is used in a wide range of wireless applications which includes remote controls and sensing. The infrared part in the electromagnetic spectrum can be separated into three main regions: near IR, mid-IR & far IR. The wavelengths of these three regions vary based on the application. For the near IR region, the wavelength ranges from 700 nm- 1400 nm, the wavelength of the mid-IR region ranges from 1400 nm - 3000 nm & finally for the far IR region, the wavelength ranges from … [Read more...]

In our day-to-day life, we all utilize different types of sensors. From that, the temperature sensor is one kind of sensor that is used most frequently in different forms like microwaves, water heaters, refrigerators, thermometers, etc. Generally, these types of sensors are used in a wide range of applications to measure the amount of coolness or hotness of the device and change it into a readable unit. Do you know how the temperature of the buildings, dams, boreholes, soil are measured:? … [Read more...]

Proximity sensor comprises all sensors that execute non-contact detection as compared to limit switches that notice objects through contacting physically them. These types of sensors change the data into an electrical signal on the movement or occurrence of a target. These sensors are used in mobile phones. Once the target is in a small range, then the lock screen of the mobile user interface will come into view which is called sleep mode. These sensors can be utilized to identify air gestures … [Read more...]
