The system measures air temperature, relative humidity, solar radiation and barometric pressure. The system consists of a base station and a wireless sensor node. WSN ethernet gateway attached to a host PC serves as the base station in the network. WSN measurement node with necessary sensors and signal conditioners serves as the wireless sensor node. The wireless sensor node measures the parameters and transfers the data to the base station. An application program has been developed on LabVIEW platform and executed in the host PC for data acquisition, processing, and plotting of the measurement data on a graphical chart. The program also saves the data in a file for history review and analysis. Hardware and software development of the system are discussed. Typical measurements with the present system are reported.

This paper presents a low cost ZigBee based WSN implementation for indoor position monitoring in a home automation application. The real-time knowledge of the location of personnel, assets, and portable instruments can increase home automation control efficiency. Position monitoring otherwise called as location estimation is the process of obtaining location information of a node with respect to a set of known reference positions. Different radio propagation models and localization techniques are discussed. Low cost Digi XBee PRO modules are deployed for location estimation using trilateration method inside a home and mean displacement error value is reported for the same. The application programs have been developed in python language using simple AT commands. The hardware and software framework and related programming are discussed in this paper.

Electronic stability control and anti-lock breaking systems in automobiles use the acceleration measurements to offer safety in driving. The system uses an ARM microcontroller to quantize the outputs of accelerometer and save the measurement data on a microSD card. A LabVIEW program has been developed to analyze the longitudinal acceleration measurement data and test the measurement system. Random noises generated and added with measurement data during measurement are filtered by a Kalman filter implemented in LabVIEW. Longitudinal velocity of the vehicle is computed from the measurement data and displayed on a graphical chart. Typical measurement of velocity of a vehicle at different accelerations and decelerations is presented.
