淋浴時動態感應燈意外關閉？

許多人都享有使用 感應開關 於浴室進行智慧自動照明控制帶來的好處。洗手或洗熱水澡後，用濕手觸摸並關閉燈光會有觸電的風險。浴室感應開關可以為我們自動關燈，實現完全無需動手的體驗。

此外，感應燈開關可以在我們夜晚需要使用浴室時自動開燈，降低在黑暗中跌倒的風險，對兒童和長者尤為重要。

目錄

• 使用超音波感應器
• 使用天花板安裝式感應器
• 設有較長的延遲時間
• 加裝濕度感應器或接點感應器
• 使用手動開關感應器

在現代家居中，每位業主都應考慮將傳統切換開關升級為感應燈開關，至少在浴室內應該如此。

想像一下，您再也不用按壓燈具開關按鈕，生活變得輕鬆愉快得多。

然而，當我們在疲累的一天後享受漫長而舒適的熱水澡時，如果浴室感應器在我們仍在泡澡時意外關燈，將會大破壞興致。

下班後洗熱水澡以舒緩壓力

為什麼會發生這種情況？

在浴室中，大多數人體感應器都安裝於靠近門口的牆壁上，以便在人員進出時偵測動作。由於這些感應器本身也是燈具開關，因此通常安裝於原本傳統切換開關所在的牆上接線盒中。

對於感應器的正常運作而言，這樣安裝並無問題；如果我們只是像使用睡房等其他房間一樣使用浴室，它們運作得十分完美。

但關鍵的分別在於，出於私隱考量及避免積水流滿整地，沐浴區通常距離浴室門口較遠，且設有玻璃門以防止淋浴水花濺出。

有些人則偏好使用浴簾來遮擋淋浴水花，並取得良好的私隱效果。

因此，在浴室中，人體感應器必須遠距離偵測沐浴區的動作，加上熱水產生的熱氣等眾多干擾源，會混淆感應器對是否有動作進行的判斷。

由此可見，浴室內的人體感應器可能無法如在其他房間般精準地偵測動作。在延遲時間結束後，感應器可能會「誤以為」室內無人而關閉照明。

That sounds reasonable, right? So how can we fix this small but annoying problem?

Here are some workarounds:

使用超音波感應器

Unlike PIR motion sensors, ultrasonic sensors can “see” through obstacles and corners and detect motion by receiving ultrasonic waves. It can normally detect motion when you shower and keep the lights on, but it is too sensitive and not quite suitable for home-usage.

使用天花板安裝式感應器

A ceiling occupancy sensor is better at detecting motion from top to bottom, it works better at detecting movement in the bathroom, but the installation requires some work. 

If you have a high ceiling, install a ceiling sensor takes time.

If you don’t have a wall box on the ceiling already, you need to use a wireless sensor/switch combo to install the ceiling sensor successfully.

And you need to find a good location for the ceiling sensor to cover both the bathing area and the rest of the room.

設有較長的延遲時間

Most people would simply adjust the time out/time delay to a longer period to keep the lights on, for like 20 mins. 

But you have to change the time delay back to normal, like 5 minutes when you finish the shower, because 20 minutes is too long for daily usage.

Set a longer time delay when showering and set it back after.

That would temporarily solve the problem, but you need to change it twice every time.

And there are people who enjoy a hot bath for way longer than 20 minutes.

加裝濕度感應器或接點感應器

Some people prefer to add another sensor to individually control the light when showering. 

For example, some may add a humidity sensor to keep the lights on when humidity is high. Some people prefer to add a contact sensor to the sliding door of the shower area to make sure the light is on. Others might like to use a water leak sensor to detect water.

This solves the problem, but maybe not in a very wise way. It takes so much extra money and works for buying and installing another sensor, solely for the water detection.

Add more sensors to control the lights but it needs more spaces and wall boxes.

使用手動開關感應器

Maybe it’s the best solution?

What if you can take your shower for as long as you like or enjoy a long bath and take a good read?

You don’t have to worry whether the sensor can or cannot detect your motion or time delay anymore!

With a manual on/off function sensor, you can turn your occupancy sensor into a normal mechanical light switch by just pushing one button.

Push one more time, the sensor will work as motion detection mode like nothing is changed.

What’s the more exciting about our sensor is;

An all in one occupancy and manual on/off sensor switch to solve all problems in one unit.

Many sensors claim to have a manual on/off control, but they are all temporary. The sensors could only work as manual mode for a short given time.

But if you can have an occupancy sensor with a “permenat” manual on/off feature like the good old toggle switch? Even better!

With Rayzeek 3-in-1 occupancy sensor switches, before showering, you can simply press a button to turn the sensor into manual mode to keep it on, or even keep it off if you want to enjoy a night bath.

You can take as long as you need, when you’ve done bathing, by simply pushing the same button, the modern, energy-saving occupancy sensor is back to work!
