AcuRite 5 in 1 Remote Sensor Repair

- Tips on fixing your remote sensor when the temperature is stuck at -40 and does not change. The problem I had was corrosion on the temperature/humidity board within the unit.
I am not going to explain how to open your remote sensor. Jordan U has a great video on two other problems (broken anemometer cup and noisy fan) so look at that where he explains in detail opening the unit

This issue has struck my unit twice since I got it in 2013 or so. This time I have coated part of the PCB to hopefully eliminate future corrosion.
The repair here takes some pretty good soldering skills and a VERY fine tip soldering iron because I had to actually solder right to the chip since the PCB (Printed Circuit Board) pads were gone.
But, there is an alternative that should work but I have not tried it yet. The temperature humidity sensor used in this is a rather common rather inexpensive little chip you can find on ebay. Note that on the board in the AcuRite unit the ribbon cable that solders to the board has pins labelled SCL, SDA, VDD and VSS. VDD is the power input, VSS is the ground. SCL is the serial Clock and SDA is the serial data. Very important that these match the replacement board so you are looking for a board that has SCL, SDA, +, - in that order. The following looks to be suitable.

Most of the boards on eBay or Amazon are like this one

Should work BUT you would have to reverse + and - wires from ribbon cable which is not that easy.
I posted this repair a while back on the AcuRite Community Forum but when I went back to look at what I had posted I found they have deleted their forum so I am posting this here.
Apologies for the background noise on much of this, I was 3D printing face shields PPE for COVID-19 pandemic.
Very informative. Thank you! I nail-polished my outdoor-light PCB. Working great four years later...
My temperature has recently started reading about 10c high. The humidity is fine just the temp. Also has recently started going through batteries like mad lately. Time to open it up and have a look, thanks for helpful video.
XLNT! Just what i was searching for. Thank you!
Glad it helped.
SDA and SCL are data lines on a common data bus known as I2C. A replacement board would need to have both the same bus address as the original as well as the same data range on the replacement chip, as you can't reprogram the firmware that reads the chip. It's a shame how many of these boards corrode away, as they're clearly exposed to the elements. Maybe Acurite should invest in some conformal coating. Or nail polish.
I did successfully replace the stock temp/humidity sensor with this $7 board from Amazon. The factory I2C address programmed into the chip is compatible with Acurite firmware.
Well made video and repair! Thanks!
Thx.
I have a different model but it has the wireless weather station dealio and it either shows the max temp or -40F. It's annoying. I had to climb up on the roof to get the SOB down in snow. The next step is to see if it has similarities. The wind speed does function.
Good luck. Hopefully not snow covered like our roof right now.
@@tjones99 Well, in Wisconsin it is actually raining and the snow is strangely almost gone.
I discovered it would connect quickly on just battery power, and it stayed connected. When I plugged in the a/c power it would freeze up or would not connect at all. I checked the output of the a/c power adapter and it showed the output at over 8 volts. I used another power adapter that was outputting at 5 volts and so far, for 24 hours it is working and has stayed connected.
Thanks for sharing.
I just had the same issue with my Youshiko weather station, after just one year! Tried replacing with a DollaTek 2Pcs High Precision AHT25 but it didn't work. Do you know if there are any probes that are compatible with Youshiko weather stations? Or how I would even find out? Thanks!
Does your Youshiko also use the SHT21 chip for temp and humidity? If so then a quick glance at the datasheet for the SHT21 shows its I2C address is 40 and the AHT25 datasheet shows its I2C address is 38. I searched for devices with I2C address 40 and that led me to this page which might help. www.mysensors.org/build/humidity_si7021
Hello can you tell me where to get the temp/humidity chip ?
I am having the same issue and have ordered a new sensor board - would you suggest covering the board with nail polish ?
I would but be careful not to cover the chip. Just the printed circuit board itself.
Hola si pueden ayudar acurite pro 5 in 1 se le agotan las baterías rápido contadas la marcas hace lo mismo .
Are you talking about the batteries in t he remote station or the batteries in the base station?
¿Está hablando de las baterías de la estación remota o de las baterías de la estación base?
@@tjones99 es de sensor acuri esta en patio afuera la batería se descarga en varios días

Si este es un comportamiento nuevo, sugeriría verificar cada placa de circuito en busca de corrosión por el clima, ya que eso puede causar rutas conductoras o puede hacer que los chips lógicos y sensores entren en estados no válidos que pueden descargar las baterías. Por ejemplo, un rastro corroído en una placa de circuito puede dejar flotando un pin de un circuito integrado, lo que puede provocar un drenaje de corriente excesivo en otras partes del circuito integrado. Y lo siento, solo uso el traductor de Google.
@@tjones99 ok te estoy agradecido por tu información un saludos desde la isla de Puerto Rico .
