Introduction to Various Types of Sensors Before working with sensors on any project, we must know its usage, advantages, limitations and characteristics. There are various parameters on which a sensor is chosen for any particular application like cost, size, weight, resolution, sensitivity, etc. In the presentation given below, the presenter will be explaining these various parameters in details along with different types of sensors available in the market like: Position Sensor Potentiometers Encoders Optical encoders Displacement Sensor Velocity Sensor Tachometers Acceleration Sensor Force and Pressure Sensor Torque Sensor Touch and Tactile Sensor Proximity Sensor

The Biggest Challenge Today is The “Lack of Hardware” With the expansion of the Internet of Things (IoT), we are looking at an ecosystem filled with sensors geographically distributed over large areas. This calls for a wide-area network (WAN) bridged by low-power communication technologies. Paromik Chakraborty of Electronics For You spoke to Gaurav Sareen, country director-India, Sigfox, to understand benefits of low-power wide-area network technologies and how the Indian ecosystem is adapting to these. Communication is a function of two things-transceiver and connectivity itself. Let’s take the simple example of your mobile service: First, you pay for the cost of the cell phone that has the transceiver embedded in the device, and then you pay for the connectivity to the network provider. New technologies are trying to address these cost points and bring them down. To give you a clear idea, our transceiver costs just about 1/15th of a cell phone transceiver’s price. Typicall...
