The module is based on a touch-sensing ic (ttp223b) capacitive touch switch module. In the normal state, the module output low, low power consumption. When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. Technical details: Low power consumption. Power supply for 2 ~ 5.5v dc. Can replace the traditional touch of a button. Four m2 screws positioning holes for easy installation. Typical high voh = 0.8vcc. Typical vol = 0.3vcc. Output sink current: 8ma. Output pin pull-up current: 4ma. Response time (low power mode): 220ms. Response time: 60ms.
