Overview
A wireless door sensor and chime built around a simple trigger-on-open design, aimed at parents, families caring for someone with dementia, and small shop owners who want a heads-up when a door is used.
SanJie keeps the feature set tighter than some competitors, 26 chime tones instead of 58, but keeps the practical basics: pre-paired hardware, adhesive mounting, an LED indicator and a memory function that holds the chosen tune through a power cycle.
- 500 ft rated wireless range
- 26 tones, 5 volume levels
- LED indicator plus memory function
- Multiple sensors can share one receiver
Who it's for
Reasonable for anyone who wants one or a few door alerts without needing dozens of tone choices, whether that is a bedroom door, a shop entrance or a back exit. Less suited to someone wanting the widest tone selection or true motion sensing.
Pros and cons
- Pre-paired sensor and receiver, quick setup
- Memory function keeps chosen tune after power loss
- Additional sensors can be paired with distinct tones per door
- 500 ft rated range
- Fewer tone options than 58-chime competitors
- Contact sensor only, no motion detection
- Adhesive mount rather than a hard-wired install
Performance notes
The sensor and receiver arrive pre-paired, so installation is peeling the adhesive tape and sticking the sensor to a door or window before plugging the receiver into an outlet. SanJie specs a 500 foot range, 26 tones across 5 volume levels up to 110dB, an LED indicator, and a memory function that keeps the last chosen tune after the receiver is unplugged. Additional magnetic sensors can be paired to the same receiver, each with its own assigned tone, so different doors are told apart by sound.
