Object Motion Direction Identification Circuit

Published:2011/5/9 2:42:00 Author:Sharon | Keyword: Object Motion, Direction Identification

Place two objects of similar resistance and performance on the same side of the object motion path, with an appropriate distance from each other. The relative position of the other side is installed two light sources respectively, so that objects between the light source and photosensitive resistancemove move in direct line. The circuit in the figure can judge the direction of the moving objects. The circuit is formed by two parts: bridge and the polarity discrimination. Rs1, Rs2, R1, R2 and Rw form the bridge, E0 provides power supply and A, B-side output. Before measuring, make Rs1 and Rs2 in the same shade or light, adjust Rw, so that the bridge is balanced. UAB = 0V. When measuring, when the object move from the bottom to up, Rs2 is the first to be shaded, resistance increases, Rs1 is in light, resistance is less, and bridge is unbalanced. UA> UB, UAB> 0V, the VT1, VT2 is ended, VT3, VT4 get through, relay J1maintains the off state, and J2 pulls. When the object continues to move upward to the Rl position, the opposite, J1 pulls, J2 opens. If the object conducts the top-down movement, contrary to the above, J1 is prior J2 to pull. Thus, J1 and J2's pull sequences can determine direction of objects movement, and provide the corresponding switching control signal output.   (View)

Beam Blocking Alarm Circuit

Published:2011/5/9 2:59:00 Author:Sharon | Keyword: Beam Blocking, Alarm

As shown in the figure, when the photosensitive resistor R4 is irradiated, the resistance is low, thus, transistor VT1 and one-way thyristor SCR are closed; when the beam is blocked, the base voltage of VT1 increase, VT1, SCR is conducted, and audible alarm buzzer BZ is energized. S1 is the reset switch. Press S1, the circuit stops the alarm.   (View)

Time-setting and time-saving switch circuit

Published:2011/5/9 3:38:00 Author:Sharon | Keyword: Time-setting, time-saving, switch

Nowadays, the door and light are mostly controlled by manual switches. Frequent forgetting to turn on or off the lights result in inconvenience and energy waste. If we can increase the light control and timing functions of them, automation and energy-saving effect can be achieved. Ready-made light control timer ICMG2001B is suggested here. It is a cheap 1h ~ 36h9 block optional timing and delay IC. The external circuit is simple with a light-driven port, photoresistors interface, low-cost 32.768kHz crystal as clock source, and the time accuracy is up to one hundred thousandth and it's very suitable for making lamps automatic control circuit. According to actual situation, choose the basic 4 block time (1h, 3h, 5h, 8h) plus one switching function to form a 5-speed light control timer circuit, and then install them into the normal 5-speed surface shell to make a 5 block light control timer switch so as to control the door lights or street lamps. Circuit is as shown in the figure.   (View)
