[Tuya Smart] Mini Humidity Temperature Node

Overview

An ultra-small wet temperature node based on zigbee.

Sensor:SHT30

Main control chip: TYZS5

Communication method:ZIGBEE

Communication chip: TYZS5

Power supply: 14200 lithium iron phosphate rechargeable battery

Charging chip: CN3058E

The last training camp happened to do the same wet temperature node, but that one used SHT31, which is more expensive and very large.

This time I just took this opportunity to optimize it.

Using Tuya Smart's development-free solution, 0 code is convenient and fast.

Regarding the main control, in fact, I also want to make an MCU through the zigbee communication module, but I really don’t have time to type the code, so I can only choose the development-free solution. If I have time, I can’t be a repeater !!

Regarding communication methods, I am also optimistic about WIFI communication, or BLE with low power consumption is OK. After all, not everyone has a ZIGBEE gateway.

But when I think about my ultra-mini module, it is only slightly larger than the Tuya module. The battery of this 14200 is only 150mah at most. I can't charge it every one or two weeks.

Zigbee has low power consumption and is so delicious!!!

As for communicating with WIFI, I will definitely do it next time, I will definitely do it next time ( What? You said I won’t necessarily do it next time? I’m not! I didn’t! You’re talking nonsense! )

I dug a groove between the charging module and the humidity temperature node so that after charging, I just need to break it off and the charging module will become more compact, just like a rocket without its thrust device. As for secondary charging, you don’t have to Did you see that I left a 2.54mmX2 pad on it?

Just connect two alligator clips to charge the wet temperature node.

How it looks like charging

Power on and configure the network.
Since I canceled the distribution button, I need to manually short the pad R12 and wait until the indicator light flashes and
the connection is connected. Then you can see the temperature and humidity.
