Wireless TPMS Tire Pressure Monitoring System

[ice15]

Kuha ka na sir. Ako rin hesitant nung una kung need ko ba talaga yun or hindi. Ngayon, pagstart pa lang ng kotse kita ko na kung need ko ba magpahangin muna or okay pa gulong ko.

naisip ko kasi... paano kung mali yung pressure nung gasoline station?
so best case scenario for me is bumili ng sarili kong pump (additional $$$ nanaman)

tapos sa car naman... paano kung di pantay yung pressure

In my case, there's tint between it and the glass so solar charging is not efficient. What I do is charge it using USB every couple of months or so pag nakita ko 1-2 bars nalang. Yung solar charging still works to some extent kasi it extends the battery capacity so madalang ko lang i-charge using USB.

yep. That's my modus too.

THere are times i even pull out the unit out of the truck if i know it will be in the garage for a lengthy amount of time. I just opt to usb charge the tpms from time-to-time on my home ofc desk.

It's a hassle to reset the units and the air tire parameters whenever the tpms monitor loses its juice & dies on me.

do what you gotta do so you can do what you wanna do

I've decided to pull the trigger and ordered the solar powered one with the USB charging option.
I got into the habit of checking each tire manually so I hope this would be a better alternative.
At the same time bought 2 sets (10 pcs.) of CR1632 batteries as they are said to last for only 3~6 months.

Three months ago i bought a cheapo solar tpms on lazada and installed it to one of our service vehicles. After 3 weeks tumawag driver na may audible alarm. It's not the low pressure alarm but the high temp. Pinadala ko agad sa talyer and turns out nag stock ang front left brake caliper piston kaya mabilis numipis brake pad on that wheel. This tpms saved me a rotor.

Medyo ot pero saan ba nakakabili nung mga stainless steel pito? Gusto ko palitan iyong rubber valve stems eventually ngga gulong ko.

May nakita ako sa lazada pero not sure kung for motorcycles siya. Or pwede din ba iyong mga iyon para sa kotse din?

Pang iwas na din ng possible slow leak kasi medyo mabigat din iyong sensors ng external tpms.

standard size yun.. sa kotse, motor, bisekleta..

Ah ok. Standard size pala iyang pito for all. [emoji16]

Salamat bro

Ang weak point naman dyan is yung rubber seals.. lagay mo ng silicone grease para di agad matuyot yung seal

errr,
whypo?

i have been using the stock brass whistles since forever.
ok naman. usual wear and tear.
over the decades, i have had to replace only but a single digit's number.
ang na-lalaspag ay ang rubber parts at hindi yung pito mismo.

Yung nut na lock ng external TPMS ko stripped the thred ng pito ng gulong namin. LAst weekend, ayaw na kumapit nung sensor kaya lumuwag at sumingaw ang hangin at nag alarm ang TPMS...

so ngayon, naghahanap din ako ng mas matibay na pito.

Yung sakin di ko na nilagay yung anti-theft nut. Hassle tanggal-kabit eh. I just make sure na mahigpit sila bago ako puamsok ng sasakyan.

Nakakatuwa lang pag nagsasalita yung app pagbukas ng head unit. "Tire pressure and temperature is normal. Enjoy your driving."

[baludoy]

^ naks! voice assisted pala ang tpms mo. Iyong akin hanggang beep lang [emoji16]

Pero yeah, tempting nga hindi na ilagay iyong lock nut kaya iyong akin hindi ko na tighten masyado iyong nut at iyong sensor. Ako Lang naman din kasi top-up ng air every now and then.

Come to think of it, Sa more than 5 years ko gumagamit nitong external tpms, wala naman atang nagka-interest sa sensors ko. Hindi naman din kasi siya eye catching even for a naughty kid - i'm guessing. Pero sabi nga nila, "never say never".

Sa android head unit kasi nakainstall yung monitor kaya may option na lagyan ng sound. Hehe.

So far sakin din, sa 1 year+ na di na nakakabit yung nut, wala pa naman nagka-interes.

Ganito yung gamit kong TPMS.

Sa baba nung tire pressure, dun lalabas kung no signal, may leak, high temp, low batt, etc. at magkukulay red yung broken lines na nakapalibot sa circle.

Yung sensor walang pinagkaiba dun sa external na solar yung monitor. Ang bluetooth receiver nya is kamukha ng GPS module ng aftermarket head units.

Dito ko nabili yung akin. Nagcheck ako sa shopee ngayon at marami na rin dun. Nung bumili kasi ako noon, kaunti pa lang sa shopee eh. At mas mahal pa benta.

mukhang mas ok yan app mo e

My main concern right now though is yung mga sensor mismo or their effect on the rubber stems.

May nabasa ako na napunit yung rubber ng valve stem or pito due to the sensor weight.

How I wish this was brought up a week ago before ako nagpadala sa sales talk ng mga tsikoteers. ;p

Put adhesive rubber as stopper so the stem doesn't flex at high speeds. Problem solved....

[gearhead000]

So decided to push through with my plan to install an external TPMS with solar charging like the following.



The rear sensor readings are quite accurate. I have the rears inflated to 32psi and sensors read 31~32 psi.
Problem is with the front sensor readings. I have them at 36psi and both are off by 2~3psi.
Temperature reading for the LF is also off. All the sensors are reading 24~28° while LF is at 30~33°C.
I tried swapping sensors at yung rear sensors do read the fronts correctly at 36psi.

I went with the external one mostly due to the convenience, not having considered the safety issues.
Also, I didn't realize how relatively easy lang din pala ikabit yung internal sensors.
Of course, you might have to do it via a tire shop to properly fit them, albeit with minimal cost I guess.
Found one at Lazada na mas mahal lang ng kaunti sa mga external TPMS at Android TV based na siya.

UPDATE: Medyo nag-stabilize na yung mga sensors. Still yung fronts, one is off by 2psi at yung isa ay by 2.5psi naman.
Yung mga temp readings not sure din kung accurate. Malamig naman kagabi pero parang mataas ang temps indicated.

Iniwan ko sa ibabaw ng dashboard yung base unit kahapon para sana mag-charge via solar.
Maybe not a good idea. Ang init nung unit which may not bode well for the batteries and the display.
Di rin naman gaanong nag-charge in that 4 hours or so na exposed directly sa sunlight.
So sinaksak ko na lang sa charger via micro USB until mag-fully charged.

Meron akong ganyan gagamitin ko nga sana as rubber feet nung base unit.
Kaso yung adhesive natuyo na yata kaya ayaw na dumikit.
I was thinking sana of using silicone sealant to build up around the valve stem.
