MH-Z19 Teardown | MySensors Forum

· I just wanted to share some information on the hardware of the popular MH-Z19 sensor. The software part is well covered in : MH-Z19 CO2 sensor and in particular in : MH-Z19.. As my sensor showed a discontinuous rise in CO2 concentration in my closed bedroom during a typical night (which is illogical) so I decided to open it.

· I have several devices flashed with Tasmota, and noticed it supports MH-Z19 out of the box, so that I flashed to the devices using Tasmotizer. Supporting this sensor required the image , which can just be selected in Tasmotizer. ESPHome, ESPEasy or ESPurna generally allow more flexibility but didn't have any special needs (for now).

MH-Z19 CO_2 and Temperature Sensor — ESPHome

MH-Z19 CO_2 and Temperature Sensor. ¶ As the communication with the MH-Z19 is done using UART, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the MH-Z19 and the tx_pin connected to the RX Pin of the MH-Z19 (it’s switched because the TX/RX labels are from the perspective of the MH-Z19). Additionally, you need to set the baud rate to 9600.

Live Well Operation Z18 | Nitro & Tracker Boat Owners Forum

· With it open water will enter the livewell, 6" maybe, depending on your load in the boat since the inlet and bottom of the livewell are below the water line when on the water. At the back you have a drail and an inlet for the incoming water (should have a screen installed over that intake port). The other one is simply a drain. You shouldn't have to put a plug in the bottom of the livewell tank unless …
