Heltec Automation HTTM-SCB CapacitiveTouch Sensor Capacitance Switch Button Module With Blue Light

10:57:54 Tim 2017/8/8 10:57:54 <p>HTTM series touch key module has the following features: <br>1. There is no mechanical parts, no wear, infinite life, reduce maintenance costs later; <br>2. The sensing part which can be placed in any insulating layer (usually a glass or plastic material) behind, it is easy to seal with the surrounding environment into the keyboard, in order to play the role of moisture and water; <br>3. The panel arbitrary pattern, button size, any shape design, characters, trademarks, and other transparent window with arbitrary, so that the overall stronger sense of product; <br>4. Compared with the physical buttons, touch buttons and more difficult to damage;5. You can modify the resistance of the back, adjust the output signal of the latch output or keep the output level (see 3.3.2); <br>6. + 2.7V ~ + 6V wide input voltage range, + 3.3V signal output can be directly used to drive relays, optocouplers, LED lights and other original documents; <br>7. -30 ~ + 70 ℃ operating temperature range;8. The touch sensitive, no lag, delay, flicker and other adverse reactions; <br>9. Built-in anti-jamming algorithm, with excellent anti-jamming performance. <br><br>Operating voltage: + 2.7 ~ 6V <br>Working temperature: 30 ~ + 70 degree<br>OUT pin output voltage: + 3.3V ± 0.1V <br>OUT pin Maximum Output Current: 500mA <br>Output mode selection <br>You can "select resistance mode" by modifying the back to adjust the output signal of the latch output, or to keep the output level. <br>No resistance welding - temporary mode: Touch and after OUT pin output remains high, the touchpad is lit backlight, touch again it becomes a low level; <br>0-10K resistance welding - latched mode: Touch Pad touch is detected, OUT pin will output high, the backlight is lit, otherwise OUT output low, the backlight turns off. <br>The default is not resistance welding, which is the default mode is Latched.</p>
