    Product detailed description

    It is a Shield that you put directly on the ESP-01/01S.

    For use with ESP-01 you will need to add a 10kΩ pull-up resistor to GPIO2, otherwise the readings may be unstable (false ('nan') readings).

    Includes temperature and humidity sensor DHT22.

    Specifications:

    • Operating voltage: DC 3.7V - 9V (can be powered by 3.7V lithium batteries)
    • Resolution: 16
    • Humidity measurement range: 0-100% RH
    • Temperature measurement range: -40 to +80?
    • Humidity measurement accuracy: 2.0% RH
    • Accuracy of temperature measurement: 0.5C

    Included in delivery:

    • 1pc Espressif ESP-01/01S DHT22 shield

    Remark:

    • When the shield is mounted on the Wemos D1 mini board, the heating from the ESP-01 module causes distortion of the measured values! For proper measurement, it is necessary to get the sensor at a greater distance from the ESP-01 module.
    • This product is not a standalone functional unit and may require professional installation.
    • Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
    • WiFi module ESP-01 not included

    Funguje jak ma, i když se senzor od eso zahřívá… nicméně stačí převrátit čidlo a problém vyřešen.

    Funguje, ale někdo při jeho návrhu moc nemyslel. Senzor se od připojeného ESP znatelně ohřívá. Pokud tedy celek není v prostředí se znatelnou cirkulací vzduchu, je to znát na o několik stupňů vyšší naměřené teplotě. Do uzavřeného prostoru doporučuji propojit modul čidla a ESP delší spojkou (2x4)

    Dobrý den, zásuvka modulu má 8 pólů. Nevíte, které z nich jsou pro propojení s ESP-01 použité (nezbytné)? Děkuji.

    Dobrý den, bude nutné propojit všechny

    Dobrý den, máte v nabídce nějakou vhodnou spojkou (2x4) se kterou se dostane čidlo do větší vzdálenosti od modulu ESP-01?
