Modified Programmable Toggle Switch Using a Low Power 433 MHz ISM Band Wireless Module Manzanas, Willen Mark D. The programmable toggle switch (PTS) is a system of switches for controlling electrical loads by means of interconnecting the switches, main controller, and electrical loads through a wired connection. The PTS is a patented technology that aims to provide a low-cost home automation system for the Filipinos. One drawback of the PTS was the use of twisted pairs for wiring between the remote switch and the main controller, which is cumbersome if rewiring is needed and in situations where physical wiring is not possible. Hence, the need for a low cost wireless remote switch suitable to replace the physical wiring of the PTS was realized. Many wireless technologies for home automation like ZigBee, Z-Wave, Insteon, Wavenis, and Bluetooth exist, but either with high price or unavailability in the Philippine market limits their adoption and popularity for use by the masses. The 433MHz ISM band wireless module was chosen for modifying the PTS due to low cost and its performance. The fabricated prototype was tested for functionality and reliability through simulated and actual testing procedures. It was found that it is functional and reliable due to its high success rate considering all the imposed limitations like the assumption of full battery power at the transmitter and within the acceptable distance between the transmitter and receiver. 2015 http://hdl.handle.net/20.500.12678/0000002062 https://meral.edu.mm/records/2062
