Features: Size: approx. 1.7 x 3.5cm / 0.67 x 1.38" Operating voltage: 4 - 28V Operating current: 2.8mA (typical), 3mA (max) Probe distance: 5-9m Transmitting power: 20mW (typical), 30mW (max) Output voltage: 3.2 - 3.4V Output voltage driving capacity: 100mA Output control low level: 0V Output control high level: 3.3V Operating temperature: -20 - 80 ℃ Storage temperature: -40 - 100℃ Trigger way: repeat trigger Adjustable distance, high sensitivity, the module has a far sensing distance, reliable, large induction angle and has a wide supply voltage range Widely used in a variety of human induction lighting and burglar alarm and so on. Adjustment part introduction: C-TM: Adjust repeat trigger time, default trigger time is 2s; increasing capacitor's capacity will make repeat trigger time longer; and actual counting trigger time can operate as below: Stick capacitor on C-TM, test 9196 3-pin frequency F, repeat trigger time T=(1/f)*32768. R-GN: Probe distance adjustment;connect with resistor and probe distance will become shorter; if not connect, probe distance is 7m; if connect with 1M ohm resistor, probe distance is 5m. R-CDS: Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (that is 196 9-pin) by R-CDS, CDS connects with photoresistor, you can close probe function at night. Pin definition: 3V3: 3V3 power output GND: ground OUT: control output; when probe moving objects, it will output high level VIN: input voltage, 4-28V CDS: enable control chip, lower than 0.7V, OUT will output low level all the time Package included: 5 x RCWL-0516 sensor module

Feature:   Onboard 2W mono amplifier (5V power supply up to 3W) can directly connected speakers (recommended with 4Ω3W speakers), 3.5mm gold-plated headphone jack can be accessed by headphones or external audio. With MicroUSB power supply interface, using mobile bank power or USB charger power supply, can also be used 3.7V lithium battery, USB 5V power supply. Support TF card (mobile phone memory card), U disk playback mode. With a speaker terminal without soldering, easy wiring.   1) Support MP3 format, power automatically play, led status turn to red. 2) Support U disk (tested with 32G), TF card (tested with 16G) playing mode, power default TF card mode, if the TF card does not exist automatically jump to U disk mode, and both devices are installed, you can manually set the playback mode, please refer to the key operation instructions.   Key operation instructions:   "Prev / V--" key: "short press" to switch "Previous" song, "long press" to switch "volume down" "Next / v ++" key: "short press" to switch "next song", "long press" to switch "volume increase" "P / P / Mode" key: "short press" to "play / pause" switch, "long press" for the U disk, TF card "mode" select "Repeat" key: "short press" for the "single / full song" cycle switch (no long press function)   Note:   1. Long press time about 2S 2. If you use U disk mode, the recommended 5V power supply, some U disk does not support 3.7V power supply.   Specifications:   Power supply range: 3.7 - 5.5V Product size: 45mm * 36mm   Package includes:   5 x MP3 Lossless Decoder Board
