Summary:The paper describes a simple and low cost instrumentation system for ground based cosmic ray air shower experiments. It is designed and fabricated at Gauhati University as part of a larger and more sophisticated instrumentation for a proposed 10 m × 10 m array to carry out a series of studies on cosmic rays. The system is tested on a 4-detector small prototype array with LED coincidence pulses. It is then used to determine the rate of omnidirectional air showers incident on the array. The dependence of 4-fold coincidence rate on array size is also investigated. The results of the tests are presented in the paper.
