Abstract: A heating device with VPD control for indoor residential cannabis cultivation includes a control module with a processing unit, a display screen and an IO interface; a heater for providing heat and a fan for circulating heat in response to a control signal from the control module; and a temperature-humidity sensor for sensing an environmental temperature value T and an environmental relative humidity value RH within an indoor cannabis cultivation environment. The environmental temperature value T and the environmental relative humidity value RH are transmitted to the control module in real time, and a VPD value is calculated from the environmental temperature value T and the environmental relative humidity value RH by the processing unit of the control module. The VPD value is compared with a pre-determined VPD threshold value to determine running modes of the heater and the fan to control the VPD within the indoor cannabis cultivation environment.

Abstract: An oscillating fan control system includes a holder, a stepper motor, a rotating shaft, a shaft encoder, and a controller. The controller is electrically coupled to the stepper motor and the shaft encoder. The shaft encoder can generate a status signal corresponding to a rotation path of the rotating shaft. The controller includes a reversing circuit and a driving circuit. The reversing circuit can generate a reversing signal for the stepper motor in response to the status signal indicating a deviation of the rotating shaft from a midpoint position of the rotation path. The driving circuit can generate pulse signals for the stepper motor according to a subdivision parameter and an oscillation angle. A method for controlling an oscillating fan is also disclosed.

Abstract: A monitoring system detects and measures a quantity of radical particles within a gas. A test chamber is coupled to a flow channel that transmits a gas. The test chamber defines an aperture connecting the test chamber and the flow channel, and the aperture permits a subset of the gas to enter the test chamber from the flow channel. An ionizer is positioned within the test chamber and generates radical ions from radical particles of the subset of the gas. A mass spectrometer measures a quantity of the radical ions, thereby providing a measurement of the radical particles in the gas.
