This sensor takes a continuous reading of any obstacle and settles it at output in TTL form within 2ms. The sensor provides easy interface of 3-wire with power, ground and the output voltage. The sensor works on 5V input Features -Very Small in size -Less influence on the color of reflected objects, reflectivity -Industrial grade quality -Can detect colour difference from certain range -TTL output high whenever sensor senses a obstacle -Detecting distance of 3cm to 80cm -External control circuit unnecessary -Low cost -Has inbuilt lenses assembly and potentiometer to set range of the module -Output indication LED -
Dynamo Hand Crank Charger E-874 Maximum Output Voltage: DC5.5V/Maximum Output Current: 600mA/Interface type: USB It is better than a solar charger because you can use it even without the heat of the sun It is great for emergency situations, for trekking, fishing, camping, mountain climbing, and even just for everyday use
