Welcome to the All About Circuits forums. There are some kinds of LM35 IC, since it is cheap and easy to find we used LM35DZ in our project. I want to design a circuit that sensor whether you hand is over the sensor and if it is it stops and holds a light display and as soon as your hand is moved it carries on. The NI Multisim Fundamental Circuits series presents many frequently used circuits and design topologies, essential in the understanding of electronics. To test the circuit, take moist cotton and place it on the sensor. In this period he has supported many electronics/electrical engineering students in their final year projects. Photo Sensor Project Question The Projects Forum. Our forum is a place I have a project I'm working on and was hoping to get some help with the electronic components. As shown in the schematic, temperature sensor of our electronic thermometer is LM35DZ. Connect the adjacent tracks of the touch pad to points A and B using thin wire. It measures from 0°C to 100°C with a very linear output graph.For one degree change, For proper operation, voltage values of the nodes shown in the circuit must be adjusted to 90mV, 190mV, 290mV and 390mV by using multiturn trimpots. This circuit can be used as an Infrared beam barrier as well as a proximity detector.The circuit uses the very popular Sharp IR module. Shown in the circuit are for the Sharp module only. Keep the touch pad in the place that is to be monitored. Dew (condensed moisture) adversely affects the normal performance of sensitive electronic devices. Touch pad can be a small piece of Strip board. Tiny Dew Sensor Circuit Diagram. Green LED lights if there is sufficient moisture.
