Gelsonlab HSTM-065 ပညာရေးသိပ္ပံကစားစရာမုသားရှာဖွေစက်စမ်းသပ်မှု
 
လိမ် detector စမ်းသပ်မှု makes use of the characteristics of human lying, such as pulse acceleration, blood pressure rise, subcutaneous sweat gland secretion increase, which leads to skin sweating. Through the skin resistance on the finger to detect the change of contact point, through the oscillation comparison circuit to realize, understand the characteristics of human lying and the application of electronic circuit.
