...it voltage of solar panel: 5.8V, working current of solar panel: 20-200ma) or external 5V 500mA adapter can be used for charging. If it rains for a long time, the adapter can be used for charging. When charging, the red indicator light is on.
When fully charged, the green indicator light is on..
Easy to Operate: The sensing distance can be up to 10 meters, depending on the size and temperature of the animal. (the larger the animal, the farther the distance, the higher the temperature, and the closer the distance.) Infrared sensing angle: 110 degrees. Sensitivity and sensing distance are adjustable..
