About this item

【Easy Installation】The sensors and receiver are pre-configured at the factory, so you only need to install the 4 sensors directly onto the corresponding tires, with no additional operations or complex engineering setup required! The receiver, in sleep mode, will automatically activate when it detects the vehicle's start-up vibration signal.
【Six different alarm modes】: SEACOT utilizes wireless transmission technology with a 0.3-second rapid response time. It includes rapid leak alarm, slow leak alarm, high-pressure alarm, high-temperature alarm, sensor malfunction alarm, and low sensor battery alarm. It is a reliable tool for maintaining tire health and ensuring driving safety.
【Solar and USB Charging】: Two charging methods ensure your safety without occupying the car cigarette lighter socket. With very low power consumption, occasional sunlight is sufficient to meet charging needs. It also features a USB charging port to ensure uninterrupted power supply.
【Color Digital Screen】：Featuring an LCD digital screen, data is clearly displayed, making it easy to read both day and night. The display automatically turns on when the car starts and turns off when the car is stationary, requiring no manual operation. Pressure and temperature data can be switched (pressure units: PSI/Bar, temperature units: ℃/℉), allowing you to monitor the data of all four tires at any time.
【Strong Pressure Detection Range and Precise Signal Transmission】The seacot S21 provides precise tire pressure monitoring from 0 to 87 PSI, suitable for nearly all types of four-wheel vehicles including sedans, MPVs, SUVs, pickups, and RVs. This tire pressure monitoring system operates at a frequency of 433.92MHz and is certified with CE, RoHS, FCC, and other certifications.

Product Description

After receiving the product, do the sensors need to be paired again?

No, the pairing was completed at the factory. You only need to install the sensors according to the tire positions, without the need for any further complex pairing setup.
Is the installation simple?

Yes, it's very simple. Just install the sensors according to the tire positions. Make sure they are securely installed, otherwise, it may result in inaccurate pressure measurements.

I bought two of these to monitor all four tire pressures and two airbags. Both units work great, interesting to see the pressures rise when the tires heat up. You do have to be quick when installing the sensors so you don't loose any air.

The pressure shown on the little screen as always exact, and I love the fact that it beeps when it’s low on tire pressure in one of the tires.

Works fine but batteries may need replacement

these work great...seem to be perfect to lots of applications...the downside if any would be the have to change batteries about every year....they do seem to last a long time and the range is great as far as transmission .....good display clear and easy read.

Tire sensor really easy to install. I would definitely recommend anyone can do it, especially for older vehicles.

Complete junk. One sensor didn't read. One broke when twisting it on. Returned for sure.

I bought this product and one of the sensors has a dead battery, make sure you have a couple CR1632 batteries on hand when you install the TPMS system. Also, the 3M adhesive strip on one side of the display mount tore in to so one side would not stick to the windshield.

I'm not sure if it's covered elsewhere, but it uses micro-USB. The cable is short, only a couple of feet, so keep that in mind if you want to keep it powered by USB. May want to get a longer cable if you like to route and hide them.The display does not auto-rotate, so the cable must stick out the right side.I plugged it in an had to hold the power button to turn it on.As soon as I screwed on the first sensor it started beeping at me! Go figure it was my lucky tire (low). Mute the alarm and went through the rest nice and easy.The default display showed a mix of Bar and °F which was confusing. The directions tell you to hold the right arrow for 6 seconds to toggle units, but I couldn't get matching PSI and °F. Push and hold the center button to enter setup. Push the center button to move through fields. Use the right and left buttons to adjust up/down. One of the fields sets your pressure units, another field sets your temp units. The settings also set your high and low alarm levels. Long press the center button to return and save your setup.I wish it had an option for differing front/rear pressures because my truck (and I know plenty of cars out there) have different pressures for front and rear. (My case 40 front, 50 rear unless I'm towing heavy then it's 80 psi)It has high temperature warnings too, but I didn't adjust them, no idea what they should be.🤷‍♂️I'm taking 1 star off because the directions are inadequate. I was hoping the QR code on the box would take me to detailed directions, but nope. If you're like me and are trying to figure out how the settings work, then I hope you found this review helpful. (The pic without my hand is the settings screen.)I took 3 more stars off because after owning it a few weeks, the sensors don't report properly:LR = 54psi @ 5°F (Actual 47 psi @ 19°F)RR = 70psi @ 1°F (Actual 48 psi @ 19°F)Also, it reports pressure issues when they have not exceeded the TH or TL values and are within their proper ranges. I'll silence an alarm only to have it return immediately, several times (even when no alert exists.). You can see my range is between 35 to 87 psi, but in two pics, it is showing alerts within that range 🤬It's obnoxious, a distraction, and not at all useful with these malfunctions.So I give it one star because... pity, I guess.
