Hi there, I'm fairly new to electronics, just wondering if someone could offer some advice for a suitable circuit diagram for the following micro vibration sensor :- All I need is for an LED and buzzer, powered by a 9v battery, to sound when vibration is sen
hello guys, what is the best sensor to monitor a movement? for example if something moves then a buzzer sounds if it stops then silent. i was thinking a tilt sensor like SW-520D but under specific situations then it doesnt work. is an accelerometer sensor good for this work? thanks a lot!
Make use of your Tmr1 to capture Time then follow sensor Datasheet to find formular that relate time to distance..
Ive made this very basic arduino shield with buttons lights a buzzer and one temperature sensor, here goes some pictures : 104543 I also had the board done in Osh Park, its shared so anyone can order it, and the rest of the entire project, schematic pcb and softwar
The part showing the connection of 5VDC to the PIR sensor is correct. I do not understand what Uc is and to what the vibration sensor should be connected? PIR sensor output usually is a relay contact to be used to light a LED or to activate a buzzer or alarm. The vibration senor is a different device.
Dear all, I am trying to finish a project which detects weight of an object. If the weight of the object is above the required weight the light would light up. I am fairly new to electrical circuit hobby works. Could anyone suggest a way for me to get started up? Any input would be much appreciated! Thank you!
We are using MQ-6 Gas sensor in one of our project. We tried to re-use the same circuit found in one of the sites. Normally, the coil resistance is 30 ohms and when i provide supply, it goes above 500ohms. so, the output on "B' pin is high and counter starts operating.. Because of this, led is glowing and buzzer in ON. This all with the gas bu
here are two i found right away. you can google for more. it is simple really
I wired this circuit on a breadboard with Tx and Rx and with suitable wire antenna. But it is not giving any sound from receiver. I checked the transmitter circuit by replacing the Tx module with piezo buzzer, and it is working fine whenever there is a motion. How can i check whether the transmitter is sending data or not. I a
I would look at strain gauges and force-sensing-resistors (FSR). These come in a vast variety of shapes and sizes, thin films etc. You could try just putting the sensors under that wrapping tape you can buy anywhere, or take the whole grip apart and re-wrap it with the sensors under that. Then you could cut a small groove (or not) in the shaft o
I'm not familiar with inductor. I need this metal sensor for my project. Unfortunately all info I got from the internet are all about the whole device, which is connected to the buzzer. Any one here has any idea or schematic on how to create inductive loop sensor that can output an analog signal or just high/low signal to micro-controller?
Hi guys,I am doing a hobby project which is using the buzzer as my vibrate sensor. As attached picture is my connection. I want it give me high (5V) while i blow wind on the buzzer. But something seems like going wrong. The comparator circuit is not working. If i replace the buzzer into a voltage divider, it is (...)
hello, I'm doing an eyeblink sensor Please give some details of the sensor
hi i'm doing my project named air quality measuring s/m. i have two sensors mq7 & mq135,first is co sensor and later is air quality sensor. these are interfacing with pic16f877a. analog values are converted into digital and displayed in a16x2 lcd. if co value is abnormal a buzzer is on.i want the hitech c code and (...)
Hi friends, My project is to interface PIC16F877A with LM35 and when it gets body temperature between 37.5 Celsius to 40.0 Celsius, the led red light and buzzer should turn ON. If the body temperature is between 36.8 Celsius to 37.5 Celsius, the led green turn on and it will check temperature every 15 minutes once.... Can anyone one help to un
Hi, i am having a big problem which need to be solved within a week. First, i am doing a simple alarm system. When the sensor detects break in, the speaker will sounds and at the same time, the handphone that is connected to the PIC will call 999 or pre-determined number. I am done with the sensor- PIC- Alarm(buzzer). Now, i dont (...)
The piezo buzzer will need a little mod. Adding mas can change the resonant frequency and increase sensitivity of the sensor to suit specific applications. Try to glue one edge to your project and fix a bolt to the other edge. The rest of the disk (and the bolt) are not touching anything and are free to move/flex. A simple circuit to inte
Take watch PZT ; aplifie signal ; into an comparator ; and driving a relay. You set the sensitivity with the amplifier gain and the comparator level. ---------- Post added at 12:21 ---------- Previous post was at 12:18 ---------- Take a look at this site
What is the RX bandwidth of a watch buzzer PZT ?
Hi guyz! I am trying to interface lm35 sensor with PIC microcontroller and light the LED when temperature goes beyond 40 deg Celsius. I am using 16F877a pic and using compiler PICC in C language. I have done simulation on Proteus and got no results. I have write this code, can any body tell me where is the problem in this code. Thanks #
