Kettle automatic alarm circuit
When you boil water by the home gas stove, it often spills off the flame by the boiling water, and this leads to gas leak. This is a waste of energy and would cause serious accidents. Use the Kettle automatic alarm which is made by the PTC thermistor, you can prevent the accidents. 1 circuit principle The core of this kettle automatic alarm circuit is composed of the NAND IC block and the PTC thermistor, the circuit principle is as shown in figure 1. Before the water temperature meets the default value, RT's resistance is small, IC's input voltage is lower than the threshold voltage, B will not alarm. When the water temperature meets the boiling point, RT's resistance increase rapidly and higher than the threshold voltage, after 30 seconds, IC outputs the voice signal and B issues the alarm. Figure 1. Kettle automatic alarm circuit 2 Select the main components The Kettle automatic alarm circuit's RT temperature probe uses the PTC thermistor, the room temperature resistance is ≤500Ω, the standard resistance - temperature characteristic curve is as shown in figure 2.8.2. Buzzer B uses the Ф27mm. Figure 2. The standard resistance - temperature characteristic curve 3 Installation and Commissioning When you use it, put the temperature sensor end into the kettle, the alarm installed in the place where is easy to hear the alarm sound, and notic the moisture.   (View)

Straw And Feed Muller Control Circuit
For the straw feed muller used in the countryside to process the corn, straw and grass and other animal feeding stuffs, some people use two electric motor (feeding motor and cropping motor) as the power to complete the crushing job for straw and feed. To avoid the cropping motor's rotor locking, it is required that the cropping motor should run firstly for a period time, and then lets the feeding motor run. The straw feed muller control circuit introduced by this model can control the two motors' woking status automatically.The circuit's working principle is shown below.This straw feed muller control circuit is made up by knife switch Q, fuse FU1, FU2, thermal relay, AC connector KM1, KM2, time relay KT1, KT2, middle relay KA and control button S1, S2 and so on, which is shown in the picture.The cropping motor M1's main circuit is made up by Q, FU1, KM1's normally open main contactor KM1-1, KR thermal elements.The feeding motor M2's main circuit is made up by Q, FU1, FU2 and KM2's normally open main contactor KM2-1.The control circuit is made up by start button S1, stop button S2, KA, KM1, KM2, KT1, KT2 and other control contactors.   (View)

Crops Automatical Frost Protection Control Circuit
The circuit's working principle is shown below.This crops automatical frost protection control circuit is made up by electrical-contact mercury thermometers Q, control circuit and ignition component and other components which is shown in the picture below.The difference between the electrical-contact mercury thermometers and general mercury thermometers is that this kind thermometers's mercury cavity has been inserted two platinum button electrodes. One is inserted in the upside of the thermometers mercury cavity as a contactor electrode, and the other is inserted in the temperature scale line which need to be controlled as a control electrode. When using this device it should adjust the monitoring and control temperature (combustion smoke temperature) to be +1℃.The control circuit is made up by thyristor VT, resistance R1, R2 and capacitor C.The ignition component is made up by 2.5V little lamp HL and gunpowder etc. First to extract two lines from the two electrode of the little lamp HL, and also use fine sandpaper or fine grinding wheel to rub a small hole in the top of HL glass ball. Then insert some gunpowder from the small hole into the grass ball. Using a appropriate size plastic membrane to wrap up the small lamp HT, and there are about 20g gunpowder in it as the detonator for smoke material. When using this device, accumulate the smoke material on the detonator, and put some soil on the smake material to prevent the burning of smoke material starter.   (View)
