【Verified】Multifunctional temperature and humidity meter based on esp-12F

Say important things three times:

Everyone, after I win the prize, all the friends who like it will leave their email addresses, and I will randomly select a few cuties and give them some physical objects, hahaha. Of course, collect the likes first.

This thing can support all series of esp8266 series except 01 and 32. The compatibility is super strong, as long as C6 and C7 are welded.

This project uses Arduino programming throughout the entire process, the APP uses APPinventor for visual editing, and 3D printing files. If you need this, please leave your email address and I will send it to you after you like it! This thing also has NTP mode. If you need it, leave your email and I will send it to you.

The main use is that the esp12F chip is small in size and has WiFi function. By borrowing the mqtt protocol, the temperature and humidity can be uploaded to the cloud. The time can also be obtained directly from the NTP network using DS1302. However, considering the issue of power consumption, DS1302 plus sleep is used. And reduce power consumption in the form of key wake-up. The passive buzzer can play music and can also be controlled from the cloud, which is very convenient. The additional LED is packaged in warm white 5730 SMD and can be used as an emergency flashlight. The power supply interface of this device is very rich. It originally has four interfaces, miniUSB, typec, USB, and KP126 battery interface, but my sister. . . The phone is from Apple, and I have removed the typec, which can also reduce the size. The KP126 battery interface is mainly for low power consumption design in the future. The combination of this module and KP126 can directly superimpose the lithium battery charging and discharging module, allowing the clock to be separated from the USB The binding of the thread makes it more convenient to use. The overall size is about 60*40*20, and the size is quite OK. On the back is a cute kitten and a message of encouragement. You can also replace it with your favorite sentence!

The first generation board: It is only a verification version, so the sleep and low power consumption parts are not considered. The second version was made after the LDO test was successful. This is the second version after the welding was successful. Because the size of the shell is blown up, it can only be ugly. A total of three are made, two are esp-07s, which do not require network configuration, and one is esp-12F, which can upload data.

I made a thermometer and hygrometer separately, and made an APP to upload the temperature and humidity once an hour. I also added a charging interface, which can be charged with a miniUSB connector.

After modification, I found that mqtt is a bit troublesome and does not require real-time collection, so I changed it to http mode, which is for the onenet platform. After assembly, it probably looks like this: The APP looks like this: I have been using it for ten days now, and there is still power. After all, it is in-depth. In sleep mode, I feel that it is still OK to last for half a month. Yes, it uses a 1000mah lithium battery.

Because of the revision, the newly revised document is at the link below:

The acrylic model has also been set up and can be modified according to your own requirements.

That small TV doesn’t have a display screen on the front, it just has a piece of paper pasted on it. It looks nice, but the display screen consumes a lot of power, and the ink screen can’t be used.
