This IR sensor is more economical than sonar rangefinders. Yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. The detection range of this version is approximately 20 cm to 150 cm(8" to 60" a plot of distance versus output voltage is shown below. The GP2Y0A02 uses a 3-pin JST connector that works with our 3-pin JST cables for Sharp distance sensors(included) It is also simple to solder three wires to the sensor where the connector pins are mounted(see the lower picture to the right) When looking at the back. The three connections from left to right(last picture) are output signal, ground, and the power Operating voltage: 4.5 V to 5.5 V Average current consumption: 33 mA Measuring range: 20 cm to 150 cm(8" to 60" Output type: Analog Output voltage differential over distance range: 2.0 V Response time: 38 ± 10 ms Package size: 29.5×13.0×21.5 mm(1.16×0.5×0.85" Weight: 4.8 g(0.17 oz) Package includes: Infrared Proximity Sensor Long Ranges Sharp GP2Y0A02YK0F x 1 Payment: We accept payment through Paypal ONLY.

The power indicator light, sensor board is not water droplets, DO output is high, the switch lights off, dropping on a drop of water, DO output is low, the indicator light switch, Brush off the the above water droplets. Has returned to output high state. AO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall. DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain. Connection mode: 1. VCC: positive power supply(3-5V) 2. GND: negative one. 3. DO: TTL switching signal output 4. AO: Analog signal output Package Incl

Ultrasonic ranging module HC-SR04 provides 2cm- 400cm non-contact measurement function. The ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. If you are sourcing a ultrasonic ranging module. The HC-SR04 is good choose. Its stable performance and high ranging accuracy make it a popular module in electronic market. Compared to the Shape IR ranging module. HC-SR04 is more inexpensive than it. But it has the same ranging accuracy and longer ranging distance. The basic principle of work: Using IO trigger for at least 10us high level signal, The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back. If the signal back. Through high level, time of high output IO duration is the time from sending ultrasonic to returning. Test distance =(high level time×velocity of sound(340M/S) 2, Wire connecting direct as following: 1. 5V Supply, 2. Trigger Pulse Input, 3. Echo Pulse Output, 4. GND, power supply:5V DC, quiescent current: effectual angle: ranging distance: 2cm– 500 cm, resolution: 0.3 cm There are 4 pins out of the module: VCC. Trig, Echo, GND. So it’s a very easy interface for controller to use it ran
