Embodiment Construction
[0048] The convenient and simple automatic watering device components are constructed as follows: figure 1 As shown, the control box is the core, which not only adapts the power supply of the pump, but also includes the key humidity control. Only one 3-digit LED digital tube 1 with two buttons realizes simple and intuitive automatic watering soil humidity control based on humidity and upper and lower threshold settings.
[0049] The general situation of automatic watering control based on humidity and upper and lower threshold settings is: two humidity sensing electrode carbon rods 20 are separately buried vertically on both sides of the flower pot soil 14 (the implant is in the center range of the two, so that the humidity detection is fully balanced) , connect the control box through two humidity sensing electrode connection wires 7 and humidity sensing electrode connection plug 6 (can be very long). The control box uses a 3-digit LED digital tube 1 to display the current s...

The invention discloses an automatic watering control box based on mud humidity and upper and lower threshold value setting. The control box mainly takes an STC15 series single-chip computer or a single-chip computer ESP-12 with WIFI as internal processing control. The automatic control box further comprises a mud humidity detecting circuit, a peristaltic pump driving circuit, a three-digit LED digital nixie tube, a lower button and an upper button; the automatic watering control box further comprises a WIFI connecting mobile phone or computer. An automatic watering device is formed by inserting a humidity sensor electrode and a peristaltic pump into the control box. A mud humidity control operation method with one screen and two buttons is designed, a high alternate current reading circuit with alternate-excitation mud resistance measuring and an ESP-12 single-chip computer with WIFI and LUA scripting language programming language provided with NODEMCU are preferably selected, the whole set of economic device is precisely formed, the convenience and visualization brought by the WIFI connected mobile phone or computer are included, and remote monitoring using an MQTT Internet-of-Things lightweight protocol is included.
Description
technical field [0001] The invention relates to the fields of planting equipment, automatic control and WIFI Internet of Things, in particular to an automatic watering control box based on soil humidity and upper and lower threshold settings. Background technique [0002] Flowerpot automatic watering control devices are mostly found in temporary measurement and control systems or timing and quantitative watering devices, and the professional field is mainly agricultural irrigation equipment. Portable, easy-to-use compact household soil moisture monitoring equipment is rarely seen. Although the soil humidity detection insert with a printed circuit board chip is also designed recently, it is easily corroded by the soil, has many connections, high cost, and is not suitable for small pots such as fast food boxes or milk tea cups. Lots of applications. Contents of the invention [0003] This application uses a modern single-chip microcomputer, especially a single-chip microco...
