The demand for energy increased rapidly over the past few decades and the trend is not expected to stop in the near future. These made researchers focus on renewable energy sources due to the environmental pollution caused by the existing conventional energy sources. Solar energy is one of the renewable energy that has been under deep research. Unfortunately, the main problem with this solar energy is lack of efficiency. Different positions of the sun throughout the day causing the static photovoltaic modules position inefficient. This paper discusses design of two-axis solar tracking system that considers multiple input parameters such as solar radiation and photovoltaic module output power for more efficient solar tracking algorithm. Some of solar tracking system conducted by other researchers uses various types of sensors including light dependent resistor (LDR) which is not efficient and can be easily affected by external environmental factors. Instead, this paper proposes the usage of pyranometer for measuring solar radiation as one of the input parameters. The solar tracking system controlled by PIC microcontroller that collects multiple input parameters and uses developed algorithm to control stepper motor movement for optimal photovoltaic module positioning.

Model 3800 - Jinan Testing Equipment IE Corporation
The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use high precision, low friction potentiometers, and, as a result, have a wide range of factory selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They can be provided with high level outputs (approximately 2-8 VDC) or ones that mimic strain gaged devices (2-4 mV/V). When set to mimic strain gaged extensometers, the Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. The potentiometers employ a hybrid wire wound around conductive plastic, which provides excellent long term stability. The output from the extensometer is readily interfaced with most existing test controllers, and may be directly input to data acquisition systems and chart recorders. Please let us know at the time of order what type of output and connector you require.

40-265-402 - Pickering Interfaces Ltd.
The 40-265 range consists of 6, 4 or 2 channel modules (this version is the 2-channel, 1.5) that simulate the operation of a range of strain gauges making it ideal for testing strain gauge meters and a wide variety of industrial control systems. The range provides a simple way of replacing in house developed sensors with a low cost simulator having excellent performance. The 40-265 uses the same resistor bridge techniques that real life strain gauges are based on, ensuring accurate emulation under all conditions. Each simulator channel includes an independent input for the Excitation Voltage and a bridge output. The Excitation Voltage port can be driven by an AC or a DC source. The bridge circuit includes three fixed resistors and a fourth programmable resistor that can be adjusted over a narrow resistance range with fine adjustment capability and excellent accuracy. The adjustment range provided is sufficient to simulate quarter, half or full bridge circuits. The standard bridge impedances are 350, 1k, 1.5k, 2k and 3k. These modules are extremely simple to use, the variable resistor element can be programmed using a simple resistance call. The module supplies the user with the resistance value required to balance the bridge, and the resistance call to the simulator can be varied above and below this value to simulate extension and compression of the strain gauge resistor.
