When to Replace
- Sensor fails to provide readings or sends intermittent data.
- Readings for pressure, temperature, or humidity are static or inaccurate.
- Module is no longer detected on the I2C or SPI bus.
- Physical damage to the PCB or sensor element is visible.
Installation Tips
- Connect VCC to a 3.3V or 5V power supply and GND to ground.
- For I2C mode, connect the SCL and SDA pins to the microcontroller's corresponding I2C pins.
- For SPI mode, connect SCK, SDO, SDI, and CS pins to the microcontroller's SPI interface.
- To ensure accurate temperature data, position the sensor away from heat-generating components.
- Protect the sensing element from direct exposure to dust, liquids, and physical contact.
- Refer to the component datasheet for I2C addressing and register information.

Durable girls sneakers
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
These Saucony girls sneakers in fuchsia are great. The design and coloring are fun and vibrant and the cushioning on the insole is good with just enough bounce. The material and construction seem durable. The Velcro strap secures in two places so you get a snug fit without the shoe “tongue” moving around.
The sizing seems true to size. Overall these are a very solid, comfortable and functional pair of sneakers. $47, the current price, is about the price for similar products these days.

Great shoes but seem to run bigger than other styles of Saucony
Size: 4 Wide Big Kid, Color: Navy/Pink
We pretty much stick with one or two brands. I have a kiddo with wide feet, who recently wore out her size 3 wides (big kid) in another pair of Saucony shoes, but she was also right at the end of the shoe, so I went with a whole size up. She picked these. The size 4's are enormous, so we had to pick another style in a 3.5w, as these didn't have 1/2 sizes and will hold on to these for fall. I picked up another brand in 4W that actually fit really well now, but they are not as heavy duty as these. I'm hoping the next style in a 3.5 isn't too small. Love these shoes, but the sizing on them feels less and less predictable. Compared to most shoes I have always had to size down in these, but now even between styles in their brand.n

Great shoes
Size: 1 Little Kid, Color: Fuchsia, Size: 1 Little Kid, Color: Fuchsia
This is a review for Saucony unisex child cohesion FST (little kid/big) size 1. These shoes are good quality and all the stitching is on point. They fit true to size for my daughter and the Velcro snaps are convenient for a little ones. I like the color of these ones as it looks cute. They have been comfortable wear and we’ve been out for hours while wearing them. I think they’re fairly easy to keep clean. I just wipe them down with a damp cloth and they come clean easily. I think these are a fair value as well and if you’re looking for a basic pair of shoes for your little one, I would recommend them.

Great play sneaker for outside
Size: 1 Little Kid, Color: Fuchsia
These sneakers fit my daughter’s feet perfectly and she loves the color. I trust the Saucony brand as I’ve owned several pairs. They are well made and this pair is an excellent option for play sneakers. My kids are outside a lot and I need a sneaker that can handle running, climbing and occasionally getting wet. There is generous breathable mesh and the shoes dry quickly.
My daughter has slightly wider feet and these fit comfortably. I also appreciate that they are Velcro so can be put on or taken off quickly because we all know kids are impatient when it comes to playtime.
