DAYTECH Door Doorbell Sensor with Adjustable Doorbell Front Door Sensor for and Automatic Door Security 1 AC Receiver and 1 Magnetic Sensor Sensor,

[Door sensor for nursing care assistance] DAYTECH door sensors will emit a sound from the receiver when they detect the door opening or closing. Unlike types that only emit a sound directly from the sensor, this remote door sensor will notify you of the door opening or closing. [150M reception distance] I installed it at the entrance on the first floor, but the signal reaches the second floor as well. Even if I work from home on the second floor, I can still hear when the door is open, which gives me peace of mind. [Door chime with adjustable sound type and volume] You can choose from 20 melodies or a ping-pong sound, but the regular ping-pong sound is also subtle and pleasant. Five volume levels are also available, so loud sounds won't be a nuisance. [6-Month Durability] If used 100 times per day, it can be used for approximately 6 months. It uses a button battery, so if the battery runs out, you can easily purchase a new one at a convenience store. The usage time varies depending on the number of times used per day. [Versatile Doorbell Chime] Not only can it detect when your elderly parents leave the house without you noticing, but it also allows you to greet customers immediately even if you are in the back of the store, which can be a hassle if you don't notice them coming in. Easy Installation: Simply attach the door sensor to your front door and plug the receiver into a power outlet. The maximum volume of 110dB can be adjusted to scare off intruders, or you can adjust the volume to silent mode with flashing only to ensure your baby is asleep. [Expandable Open/Close Sensors] Different sets can be paired and used. One receiver can be expanded to up to 20 magnetic sensors, and magnetic sensors can be expanded with multiple receivers. [Tone Memory Function] The door chime has a memory function, so even after a power outage, the volume and melody will remain the same, reducing the hassle of resetting them. [Lightweight and small sensor] The sensor is about the size of a cigarette, about 3cm smaller, and can be attached with double-sided tape.
