Arduino IoT Development Kit

Arduino IoT Development Kit

The kit is preprogrammed to readily demonstrate all the input and output devices connected to it and offers the easiest way to develop various embedded applications.  Just plug the components onto the development board and build the custom applications in Arduino Software – IDE with reference to the pin configurations and sample codes.
The development board has been specifically designed to fit selected sensors, outputs and wireless devices.  The aim is to decrease the amount of time required for rigging up the circuits with wires and soldering, and to maximize the learning by developing various embedded IoT applications.

Temperature Senor LM35

Precision Centigrade Temperature Sensors General Description: The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ?Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ? ? ?C at room temperature and ? ? ?C over a full -55 to +150?C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35's low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 mA from its supply, it has very low self-heating, less than 0.1?C in still air. The LM35 is rated to operate over a -55 to +150?C temperature range, while the LM35C is rated for a -40 to +110?C range (-10? with improved accuracy). The LM35 series is available packaged in hermetic TO-46 transistor packages, while the LM35C, LM35CA, and LM35D are also available in the plastic TO-92 transistor package. The LM35D is also available in an 8-lead surface mount small outline package and a plastic TO-202 package. Features: Y Calibrated directly in ?
