Description of MakerFocus 2Pcs ESP8266 ESP-01 Serial Wireless WiFi Transceiver Receiver Module 1MB SPI Flash With DHT11 Temperature And Humidity Sensor Module For Arduino

This module to ESP8266 as the master, DHT11 for the temperature and humidity sensor. ESP8266 collection environment temperature and cooling upload to the server. ESP8266 ESP-01 Series is a highly integrated chip which offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor; it also has powerful on-board processing and storage capabilities; Support 3 modes: AP, STA, AP STA. DHT11 digital temperature and humidity sensor is a digital signal output with a calibrated temperature and humidity combined sensor. The digital modules and acquisition of temperature and humidity sensor technology ensures that products with high reliability and excellent long term stability. Regarding for the esp-01S: Input power: 3.3V, I/O voltage tolerance: 3.6V Max, Flash Memory Size: 1MB (8Mbit), WiFi security modes: WPA, WPA2; Regarding for the DST11 sensor:support 3.7 v-12v DC supply (3.7 v lithium battery); Measurement range: 20-90% RH 0 to 50°C. The operating example included two way: 1.Power supply: 3.7V-12V DC power supply connect to VCC GND(2.54mm pin header); 2. Download the program to ESP-01 S(this connection does not include this wireless module).

Its worth it. I love these chips

I have 2 orders for this product. When first ordered, all 1MB chips work fine; left me starving for another order. The second order contained two 4MB caches and two 1MB caches. One of the 1MB has bad usage [arrived by brick]. The two 4MB make up for the poor 1MB I got I think. In general I am satisfied with the purchase considering the unit price. For both orders, the chips came in an anti-static bag, not individual bags as the product photo suggests; ultimately a non-interfering factor. Would…

Pros
  • This module is for ESP8266 as master, DHT11 for temperature and humidity sensor. ESP8266 Acquisition of ambient temperature and cooling load on server
Cons
  • Annoys

Very nice little wifi controller!

While doing small DIY projects I didn't realize what I was missing until I discovered this one. If you want to control something wirelessly, such as For example, an LED, you typically buy a $20-$30 smart plug and a power supply to plug in, which will eventually control your LED or motor. With this module you can create a reliable and secure remote managed application in just a few hours. With Arduino Studio and other free software, you can quickly build all sorts of smart things and eventually…

Pros
  • ESP8266 The ESP-01 series is a highly integrated chip that provides a complete and self-contained Wi-Fi networking solution that allows you to either host an application or offload all Wi-Fi networking functions from another application processor; it also has powerful onboard processing and storage capabilities; Support for 3 modes: AP, STA, AP STA
Cons
  • I don't remember but there was something

None of them worked. Update all working replacements

First I tried the ESP-01 firmware circuitry I've used in the past and none of them went into AT command mode, I would see DONE but couldn't go beyond that. I tried to use an Arduino UNO as a programmer. The terminal session started as expected in AT command mode and worked fine. Then I tried flashing the example program to blink. It seemed to work, but when it was done the ESP module didn't blink and it stopped processing AT commands. updated 14.05. The seller immediately sent 4 replacements…

Pros
  • Related to esp-01S: Input power: 3.3V, I/O voltage tolerance: 3.6V max, Flash: 1MB (8Mbps), WiFi security modes: WPA, WPA2; As for the DST11 sensor: 3.7-12V DC power supply support (3.7V lithium battery); Measurement range: 20-90% RH 0 to 50°C
Cons
  • Makes me nervous

Updated review: networking products

Theses really work. programming difficulties. The best option is to use esp8266-12 for programming. I'll post a diagram of it soon.

Pros
  • Many will do
Cons
  • Not bad, but...

Neat but archaic Best in Computers & Accessories

I liked these boards but never got the most out of them. In the Senior Design course, it was difficult to learn how to load programs and it took a lot of precious time. So I suggest to use ESP8266 boards which are more proven and reliable i.e. boards with active developer communities.

Pros
  • Pleasant
Cons
  • Definitely a bad product

They all work in network products

All 4 ESP-01 have been tested with the flicker circuit and all work fine. So far I've made an IOT button with one and it's been working for a week now. You can find them cheaper but nothing beats 2 day shipping! I used a serial USB ESP8266 wifi module for programming along with a soldered button to enter programming mode.

Pros
  • Absolutely amazing!
Cons
