Go to a local electronics store, there are plenty of them in Singapore, right?

eh, I bought 2 PCB from an online store. something called leaf wet sensor. well. it works good except that when it already stop raining, the sensor is still wet and it takes like almost 1hr before it triggers a "dry" sensor state.

that's why those sensors need to have a heating element below the PCB.

Place it 45 degrees, water will drop off.

I did installed one with heating element. Low cost and works great with the Marmitek SM10

Mounting it at 45 degrees is a must indeed for the water to roll off it. You don't want it to just form a little pool on there.

@wima: do you also heat it too? because thats not done then with a sm10 right

@Snelvuur: The heating element is built into the sensor. This is powered via an external power source. The SM10 is just mounted to the relais the sensor has.

Do you think it would be possible to use the a Visonic MCT-100 and the Conrad rainsensor? (it has a 'potentiaalvrije schakeluitgang')

So the alternative is an SM-10 with the Kemo M152?

Thanks!

@estaban: yes that part i understand, but you keep it "warmed" 24/7? it has a trigger no?

Yes, it only is heated up when rain is detected, the rest of the time the heater is off.

There is another rainsensor in the Conrad shop check number 156515 I think it is only a remote sensor and it will not include the alarm circuit ....

my windows are casement non cranked type. and nope i wish i can change my windows. the government doesn't allow other types of windows except friction stop casement windows and sliding windows. not complying to regulations results in confiscation of house. yeah. that's the law in singapore

What kind of windows you prefer to use then?

Think that the rules about renovating in Singapore are the same as in Holland or even looser. When you live in subsided public housing (HDB) or a Condo you are bound to much more restrictions then with private properties. With landed private properties you can build what you want, in Holland is that only possible in the free sectors. A permission you can get it here within a week or two, in Holland my sis needed to wait for 5 months to make an little addition to her kitchen. Try in Holland to change the colors of your window or front door of a 'woningbouw' (public housing) house. A friend of mine did that and he got a notice from the authorities to change it immediately back or he has to move out! In Singapore you can change at least the colors of your windows and get a different front door. Just a note...

For the rain...I use a humidity sensor, Singapore has always a very high humidity around 75% and before it start to rain, it climbs very rapidly to 85% or higher. Combine it even with a light sensor for during daytime, sky suddenly darker and humidity raise, rain

Getting lighter and humidity drops slowly, dry again

Tropical rain showers are very easy to predict...

Thunderstorms are in Singapore more frequent and heavier then in Europe, especially during the raining season. To protect my equipment I am building now a lighting sensor so shut down some equipment when the lighting gets to close...
