Adafruit Standalone Momentary Capacitive Touch Sensor Breakout
Key Features: Single "momentary" capacitive touch sensor Red LED indicator when touched Save power by disconnecting the LED from the output pin Designed with the more-responsive "fast mode" This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. Just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e. g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn & #39; t suited to your project. If you want to save power, the LED can be disconnected from the output pin (cut the trace between the jumper marked as such). Designed with the more-responsive "fast mode", it draws about 0.5 mA. If you need ultra-low (~50uA) power usage, the mode jumper can be cut on one side & soldered closed on the other to fix it into that mode. Check Adafruit & #39; s datasheet for specific power usage measurements. Item Specifics Size: 20mm / 0.8" x 28mm / 1.1" Weight: 1.87 g

Features:; 1. It can detect the flame or the light source with the wavelength in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is. 2. The detection angle is about 60 degrees, which is especially sensitive to the flame spectrum. 3. Sensitivity adjustable (blue digital potentiometer adjustment). 4. The comparator output directly triggers the relay. 5. Dimensions: 50x42mm Thickness 19mm, with fixing bolt holes for easy installation. The 6.2 -channel output has a blue terminal block for easy wiring.; Use:; Various flames, fire source detection, 2-way relay output, can be connected to 220V high-current equipment appliances.; Electrical Parameters:; Supply voltage: 12VCurrent: greater than 200mALoad: 250V 10A AC or 30V 10A DC; Instructions for use:; 1. The flame sensor is sensitive to the flame and also responds to sunlight. It is generally for flame alarms and other purposes. 2. By adjusting the potentiometer, the intensity of the sensor & #39; s induced flame can be set. When the flame exceeds the set threshold, the relay is closed and the common end is connected to the normally open end. When the flame is below the set threshold, the relay is turned off and the common terminal is connected to the normally closed terminal. 3. Common end, normally open, normally closed, three ports are opposite to one dual control switch. When the relay coil is energized, the common end is electrically connected to the normally open end. When there is no electricity, the common end and the normally closed end are turned on. 4. Keep the sensor and flame at a certain distance to avoid damage to the sensor at high temperatures.
