    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 DHT11.

    Specifications:

    • Operating voltage: DC 3.7V - 9V (can be powered by 3.7V lithium batteries)
    • Humidity measurement range: 20-95% RH
    • Temperature measurement range: 0 to +60?
    • Humidity measurement accuracy: 5.0% RH
    • Temperature measurement accuracy: 2 C

    Included in delivery:

    • 1pc Espressif ESP-01/01S DHT11 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

    Mám problém s vysokou teplotu. První měření po připojení k napětí je OK. Další a další měření se postupně navyšují až zhruba na o 8 stupňů víc než je skutečná teplota.

    Dobrý den, U tohoto shieldu je trochu nešťastně řešeno umístění modulu ESP-01 přímo nad senzorem DHT-11 a ten tudíž vlivem provozu modulu ESP-01, kdy se začne zahřívat mikroprocesor, začne ukazovat vyšší hodnoty. Řešením je co nejvíce oddálit čidlo od modulu ESP-01.
