    Потенциал логического нуля не равен земле. Притом все три работают так же. В интернете осциллограммы глянул, там у людей нормальный уровень.

    Странно, вообще ничего общего с DTH22, который я покупал несколько лет назад. Ножки тонюсенькие, только под пайку. Ну ОК пока, посмотрим как будет работать.

DHT11:
         The DHT11 digital temperature and humidity sensor is a temperature and humidity composite sensor with a calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. The sensor consists of a resistive wet sensor and an NTC temperature sensor connected to a high performance 8-bit microcontroller. Therefore,the product has the advantages of excellent quality,ultra-fast response,strong anti-interference ability and high cost performance. Each DHT11 sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program,and these calibration coefficients are called internally during the processing of the detection signal. The single-wire serial interface makes system integration easy and fast. Ultra-small size,extremely low power consumption,and signal transmission distances of up to 20 meters make it the best choice for even the most demanding applications. The product is available in a 4-pin single-row lead package.

    • AM2301:

      Product Features:
         The AM2301 Humidity Capacitance Digital Temperature and Humidity Sensor is a temperature and humidity composite sensor with a calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. Therefore,the product has the advantages of excellent quality,fast response,strong anti-interference ability and high cost performance. Each sensor is calibrated in a precision humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program,and these calibration coefficients are called internally during the processing of the detection signal. The sensor consists of a capacitive sensing element and an NTC temperature measuring element connected to a high performance 8-bit microcontroller. Communication with the microprocessor via a single bus requires only one line,40 bits of data at a time,high first out. Small size,low power consumption,long communication distance,can be used in demanding applications.

      ESP8266 ESP-01 ESP-01S DHT11 Temperature and Humidity WiFi Node Without Wireless Module U40 For Arduino

      • Description:
        This module uses ESP8266-01 / ESP-01S as the main control,and DHT11 is the temperature and humidity sensor. ESP8266 collects the temperature and humidity in the collected environment and uploads it to the server. Support 3.7v-12V DC power supply (3.7V lithium battery). Can be used as a temperature and humidity collection node for smart home or IOT projects.
        Characteristic:
        * Master control: ESP-01 / ESP-01S (This module does not include ESP-01 / ESP-01S)
        * Temperature and humidity sensor: DHT11
        * Working voltage: DC 3.7V-12V (support 3.7v lithium battery power supply)
        * Measuring range: 20-90% RH 0-50 ° C
        * Measurement accuracy: temperature: ± 2 ° C,humidity ± 5% RH
        Application example:
        1. Power supply: 3.7V-12V DC power connected to VCC GND (2.54mm pin header)
        2. Download the program to ESP-01S (this connection does not include this wireless module)
