I had forgotten that it was even chargeable it's been so long since I purchased it. I was surprised to see the charge port when I went to replace the batteries, so I checked when I installed it, August 2019. Works great! **Q: Can I use regular batteries when rechargeable ones get bad? What size fit?** A: It uses a single 18650 rechargeable battery. Wires are soldered to battery and then plugs into circuit board. If you can solder, any 18650 can work as replacement. Battery is glued to circuit board, but with care can be removed. **Q: Are the installation instructions available online?** A: Its actually quite simple. Put in the batteries, adjust the tone you want and the distance you want it to pick up on (we ended up taking it down and switching it higher after a week) with the two small switches inside the unit, screw on the back and swivel, pick a tree, screw it to the tree, walk by it 100 times to test it. (Make sure someone is in the house to let you know if it works from inside too), plug in the inside unit or put in batteries and voila! Its good to go. **Q: can you program a time you want the sensors on or off?** A: Not that I know of - this is the simplest unit they have. However, you can determine the volume level of the base unit (the part that "alarms") or even turn the alarm sound completely off. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great *by K***N on Reviewed in the United States on October 19, 2023* Using Nicad batteries, so far works at -45 ### ⭐⭐⭐⭐ 4.0 out of 5 stars Sensitivity is tricky *by T***L on Reviewed in the United States on August 10, 2019* Installed two sensors. One of the two kept causing false alarms for no apparent reason. Lowered the sensitivity one notch to 20 - 25 feet and the false alarms stopped. Now the sensor seems to pick up movement at only 15 feet or less. Not a big issue, but I'd like the range to be accurate, as I'm using these purely as motion detectors on my property. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Excellent product, stellar customer service *by R***L on Reviewed in the United States on September 24, 2021* Bought a sensor and receiver over 2 years ago and it worked great untill the heat plus a bird beak shattered the sensor eye cover. Had to unplug because it wouldn't stop chiming. Of course I didn't get the extra protection plan at the time and the warranty expired a few months back so I went and bought a new sensor. Sadly it was not compatible with the old receiver as they have been updated. I was in contact with customer service and after we realized why it wouldn't pair, they were kind enough to send me a new receiver. I had it set up and running in about 3 minutes. Great product and customer service folks. Definitely will buy again when its time to expand our system. ## Frequently Bought Together - 1/2 Mile Supplemental Hosmart Driveway Alarm Sensor (1 Coffee Sensor only) - Driveway Sensor- Extra Wireless Weather Resistant Outdoor/Indoor Motion Sensor&Detector for HTZSAFE Alarms-1/2 Mile Wireless Transmission Range- 2 Adjustable Sensitivities, HB-T804 - Driveway Alarm- 1/2 Mile Long Range Wireless Driveway Alarm Outdoor Motion Sensor&Detector-DIY Security Alert System-Monitor&Protect Outdoor/Indoor Property - 1 Receiver and 1 Sensor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/148220243-supplemental-hosmart-driveway-alarm-sensor-1-sensor-only-coffee](https://www.desertcart.co.th/products/148220243-supplemental-hosmart-driveway-alarm-sensor-1-sensor-only-coffee) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
