i've came across to this blog whil...hi guys...<br /><br />i've came across to this blog while searching for motion sensors. In fact, i'm pretty new in electronic field or i may just say that i'm just the beginner. i have problems that needs to solve and perhaps this is my first project with the electronic features. and believe you guys the expert can help up.<br /><br />i live in housing estate double storey house with a very limited space of car porch. I have two car that are park when we're at home. Problems is i have a dog kept in that car porch as well, i don't wanna my dog to pea at my vehicle's tyre at night time cause no ones watching. so i plan to fix a line of pipe that can hold some amount of water and so it can spray a water to my dog just before he splash his pea to my cars. and that could be achieve with the help of motion sensor. the motion sensor could trigger a valve that hold the water. <br /><br />now i'm looking for motion sensors that can be attache to solenoid valve(SV) 24VDC or 240vac(this may require relay to work with), it must be able to hold 3 to 5 seconds or adjustable prior activating my SV. the operating power supply of the sensors must be 12 VDC because i have a regulated power supply right now 12VDC 5A. <br /><br />and where could i buy such sensor.<br /><br />could anyone help. please.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-236630323640582849.post-51542111422825060252012-01-02T06:16:44.222+08:002012-01-02T06:16:44.222+08:00@azmi, I've something similar posted on my fb ...@azmi, I've something similar posted on my fb page, pls go there.. it uses a CT to measure the current and send out a voltage to the analog pins..Stanleyhttps://www.blogger.com/profile/05425545478966156895noreply@blogger.comtag:blogger.com,1999:blog-236630323640582849.post-65986836894509844742011-11-29T16:53:36.594+08:002011-11-29T16:53:36.594+08:00wanna ask something about project that im been doi...wanna ask something about project that im been doing right now..about an electrical saver...im searching for microcontroller circuit using current for its indicator..can you help me to solve it...mR.

I've testing 2 types of temp sensors, a not so linear ones using a thermistor and a better one using LM35 temp sensors. Both are okay for short wires length but for a longer distance, a digital sensors using 18B20 that can have a very long wire length and all the sensors on the single wire.Stanleyhttps://www.blogger.com/profile/05425545478966156895noreply@blogger.comtag:blogger.com,1999:blog-236630323640582849.post-67920440207600606412010-10-26T20:43:30.378+08:002010-10-26T20:43:30.378+08:00Just noticed your new blog site.

Its very useful for industrial usage where certain temperature is reached, it will automatically turn on the alarm etc. Whereas turn off feature can be used to, eg. turn off the heat source whenever it exceed certain temperature. Those sensor for Diy'er can be easily purchased from online stores.PJBlokehttps://www.blogger.com/profile/10068696437830648159noreply@blogger.com
