The system consists of a weatherproof enclosure which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and Leaf Wetness, Air Temperature & Humidity sensors (One each). For the most accurate disease prediction the leaf wetness sensor, designed to mimic the surface area of a leaf, use electrical resistance to measure the level of surface moisture on foliage, whether caused by rainfall, dew, or spray. The leaf wetness sensor enables the data logger to detect the presence of surface moisture on foliage and calculate the duration of wetness. When moisture is present, the sensor detects an electrical resistance change between the gold-plated elements of the grid. This is displayed and record by the data logger as a value between 0 (dry) and 15 (wet). moisture on foliage and calculate the duration of wetness. When moisture is present, the sensor detects an electrical resistance change between the gold-plated elements of the grid.

We offer Digital Gauss meter, it operates on the principle of Hall Effect in Semi-conductors. A semiconductor carrying current develops an electromotive force, when placed in a magnetic field, in a direction perpendicular to the direction of both electric current and magnetic field. The magnitude of this e.m.f. is proportional to the field intensity, if the current is kept constant. This e.m.f. is called the Hall Voltage. The small Hall Voltage is amplified through a high stability amplifier so that a millivoltmeter connected at the output of the amplifier can be calibrated directly in magnetic field unit (gauss). Features Mag. Field Measurement Excellent Linearity IC Controlled Circuit Excellent Stability Applications Wide application in industry where accurate measurements of magnetic field is required. Measurement of steady magnetic field e.g. in loud speakers, dynamos, moving coil instruments etc. Useful in laboratory experiments involving electromagnets.
