SeNd Technology have emailed me to let me know about their cool piece of tech – a connected S-PIR sensor, that uses text messaging to alert you – nice!
The S-PIR is a self-contained motion detector with build in GSM modem for sending a SMS Text message to you when the zone is breached.
Just register the pay-as-you-go SIM card with some credit and insert into the S-PIR, plug in the mains transformer and you are ready to configure. Then by SMS change the security passcode and add your mobile number – and it’s ready.
To “arm” just “ring” the S-PIR for a few seconds and you have 15 seconds to leave the secure area. Its now armed.
When the PIR sensor next detects motion you will receive a SMS informing you. The S-PIR will then call you so you can hear (via the units built-in microphone) and activity at the remote location.

It’s got a good range of features too:
- PIR Motion Detector.
- Built-in GSM (mobile) modem – just slot in a SIM card (UK PAYG supplied with S-PIR).
- Send SMS to up to 5 numbers (you, neighbour, estate manager etc)
- Name the zone – e.g. “Home”, “Office”,” Garage” etc.
- Built-in microphone – S-PIR calls you back to allow you to listen in at the location
- Battery backup – rechargeable battery will inform you of power fail, low battery and power resume.
- Arm just by ringing from your authorised number.
- Exit delay (Adjustable).
So what do we think? I have to say, having an interest in home security myself, I really like the idea – it’s not over-complicated, but does what’s needed, in an innovative way. If there are more products like this coming online over time, we really will be able to look forward to the concept of monitoring our homes remotely.
